AME8853
n General Description
The AME8853 family of positive, CMOS linear regula-
tors provide low dropout voltage(220mV@300mA), low
quiescent current, and low noise CMOS LDO. These
rugged devices have both Thermal Shutdown, and Cur-
rent limit to prevent device failure under the "Worst" of
operating conditions.
n Features
l Low Dropout Voltage: 220mV@300mA
l Guaranteed Current: 300mA
l Quiescent Current: 60µA (typ.)
l Over-Temperature Shutdown
l Current Limiting protection
l PSRR: 60dB@10KHz
l Ultra-Low-Noise: 100µVRMS at 1Hz to 100KHz
l Low Temperature Coefficient
l Input Voltage Range : 2.5V~5.5V
l Output Voltage Range: 0.8V~ 4.3V
l Green Products Meet RoHS Standards

Pin Number Pin Name
Pin Description
1 IN Input voltage pin; should be decoupled with 1µF or greater capacitor.
2
GND
Ground connection pin.
Enable pin, Active “high". When pulled “low”, the PMOS pass transistor turns off,
3 EN current consuming less than 1µA. When EN pin float outside, it’s weakly pulled
high form internal MOS.
4 NC No connection.
5
OUT
LDO voltage regulator output pin; should be decoupled with a 1.0µF or greater
value low ESR ceramic capacitor.
