AME8820 n Detailed Description The AME8820 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current protection, and thermal shutdown. The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and thermal shutdown circuits become active when the junction temperature exceeds 150oC, or the current exceeds 150mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 125oC. The AME8820 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. High PSRR, CSP, 150mA CMOS LDO n Board layout Recommendations to Improve PSRR and Output Noise To improve AC measurements like transient response, PSRR, and output noise, it is recommended that the board should be designed with separate ground planes for VIN and VOUT, with each ground plane connected only at the ground pin of the device. n Over Current Protection and Short circuit Protection During normal operation, the AME8820 limits output current to approximately 400mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. When the output voltage is lower than approximately 0.8V,call short circuit , the AME8820 limits output current to approximately 200mA (fold back current). When short circuit protection engages, regulator operation resumes until removed the short circuit condition. Over current and short circuit protection prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package n External Capacitors The AME8820 is stable with an output capacitor to ground of 1F or larger. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be at least 1F to have a beneficial effect. n Enable The Enable Pin is normally pull-high. When disable, it pulled low, the PMOS pass transistor shut off. All internal circuits are power down. Under this circumstance, the standby current is less than 1A. This pin can't be floating. 8 Rev.B.01 AME, Inc. AME8820 n Over Temperature Protection As protection from damage due to excessive junction temperatures, the AME8820 has internal protection circuit. When junction temperature reaches approximately 150oC, the output device is turned off. Once the device has cooled down to below approximately 125oC, regulator operation resumes. For reliable operation,design is for worst case junction temperature of < 125oC taking into account worst case ambient temperature and load conditions. Depending on each package type, presenting different power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage due to overheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or inadequate heatsink. For reliable operation, junction temperature should be limited to +125oC maximum. To estimate the margin of safety in a complete Power design (including heatsink), increase the ambient temperature until the thermal protection is triggered; use worst-case loads and signal conditions. For good reliability, thermal protection should trigger at least +35oC above the maximum expected ambient condition of your particular application. This configuration produces a worst-case junction temperature of +125oC at the highest expected ambient temperature and worst-case load. The internal protection circuitry of the AME8820 has designed to protect against overload conditions. It was not intended to replace proper heatsinking. Continuously running the AME8820 into Thermal protection disables the output when the thermal shutdown will degrade device reliability.
