| MITSUBISHI PRELIMINARY M62525FP HIGH PRECISION LOW INPUT/OUTPUT DIFFERENTIAL( 3.3V, 2.5V) FIXED OUTPUT VOLTAGE REGULATOR WITH RESET DESCRIPTION Some parametric limits are subject to change. M62525FP is a monolithic integrated circuit integrating 2ch regulator and reset IC targeted for printer, CD-ROM, CD-R, PIN CONFIGURATION(TOP VIEW) and the other OA equipments. This device has 2 regulators with high precision output, low input/output differential, high 16 NC VIN1 1 current capability, and high ripple rejection ratio. Compact CH1 15 ON/OFF 2 application design is made easy by small 16pin package.

ON/OFF *Load regulation: 20mV(typ.) 9 NC VIN2 8 *ON/OFF control available for regulator output *Non-adjustment for reset detection voltage: 4.0V2% Outline 16P2N-A *Reset: monitors input voltage 5V APPLICATION OA equipments such as printer, CD-ROM, and so forth Note:Same voltage should be applied to VIN1,VIN2,and VIN3. GND terminals(4pin, 11pin, 14pin) should be put together to be connected to GND. VIN2 VIN1 1 8 VIN3 5 + O N / O F F - Err. Amp. Overcurrent limit circuit 15 Output1 CH1 ON/OF F 2 + O N / O F F - Err.

R is a pull-up resistance for reset terminal. 2.2kohm is recommended for the value. Note2. C1 works for stabilizing input voltage. Recommended value is 10uF. Note3. Co works for preventing the output voltage from oscillation. Minimum value is 10uF. Recommended value is 47uF. Note4. Delay time for reset is changeable by the capacitance connected to Cd terminal. Even when no capacitor is connected, 30usec.(typ.) delay time is available. Below shows how to set the delay time. Delay time:Tpd(ms)=0.23xCd(F) Example:when 0.1uF is connected to Cd terminal. Tpd(ms)=0.23x0.1(F) =23(ms) Note5. Connect ON/OFF terminal and VIN when ON/OFF function is not needed. Note6. Get the capacitors close to IC terminals in case the operation is not stabilized by the wiring resistance between each capacitor and IC terminals. ( 4 /4) 000530 |
