| DATA SHEET DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT PC24A00 Series THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR The PC24A00 Series is a low dropout voltage three terminal regulator that has realized a minimum voltage differential between the I/O of no more than 1 V when the output current is 2 A through the employment of a PNP transistor at the output stage. Due to its ability to achieve a greater reduction in the power loss compared with conventional three-terminal regulators, the PC24A00 Series is ideal for use as the secondary side smoothing circuit of a power supply.

When operating junction temperature rise up to 150C, the internal circuit shutdown output voltage. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded. 2 Data Sheet G14632EJ3V0DS00 PC24A00 Series TYPICAL CONNECTION D1 INPUT CIN PC24A00 + OUTPUT COUT D2 CIN: 0.1 to 0.47 F. Be sure to connect to prevent abnormal oscillation. When using capacitors, film capacitors with excellent voltage and temperature characteristics are recommended. Be aware that some monolithic ceramic capacitors have inferior temperature and voltage characteristics. When using a monolithic ceramic capacitor, CIN requires a capacitor that can secure this capacity within the voltage and temperature range used. COUT: 10 F or higher. Be sure to connect to prevent oscillation and to improve transient load stabilization. Remark Connect CIN and COUT as close as possible to the IC pins (within 2 cm). D1: D2: VO > VIN required Shottky barrier diode required for when VO < GND.

However, if the device is operated in a way that exceeds the recommended operating conditions, the margin between the actual conditions of use and the absolute maximum ratings is small, and therefore thorough evaluation is necessary. The recommended operating conditions do not imply that the device can be used with all values at their maximum values.

For the details of the recommended soldering conditions, refer to the document SEMICONDUCTOR DEVICE MOUNTING TECHNOLOGY MANUAL (C10535E). For soldering methods and conditions other than those recommended below, contact your NEC sales representative. Through-Hole Device PC24A05HF, 24A12HF, 24A15HF: 3-Pin Plastic SIP (MP-45G) (Isolated TO-220) Process Wave soldering (only to leads) Conditions Solder temperature: 260C or below, Flow time: 10 seconds or less. Caution Apply wave soldering only to the pins and be careful not to bring solder into direct contact with the package. CAUTION ON USE * In the PC24A00 Series, if the output is short-circuited at VIN 20 V, the output may not be restored after the shortcircuit is cancelled. In this case, restore the output by lowering and then reapplying VIN. * If a lower than recommended input voltage is used in the PC24A00 Series, a large circuit current will flow due to the saturation of the output stage transistor (refer to the reference characteristic curve of the IBIAS - VIN characteristics). The capacitance for the input side power supply therefore needs to be only enough to enable the current to flow in this circuit at startup. Note also that a resistor cannot be inserted at the GND pin to adjust the output voltage.

NEC Corporation assumes no responsibility for any losses incurred by the customer or third parties arising from the use of these circuits, software, and information. * While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. * NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. M7 98. 8 |
