500mA LOW NOISE LDO REGULATOR
General Description
Features
AP2213
The AP2213 is a 500mA output current fixed voltage · Up to 500mA Output Current
regulator which provides low noise, very low dropout · Low Standby Current
voltage (typically 350mV at 500mA), very low
standby current (1µA maximum) and excellent power
supply ripple rejection (PSRR 75dB at 100Hz) in bat-

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.

Note 2: Specifications in bold type are limited to -40oC≤TJ≤125oC. Limits over temperature are guaranteed by design, but not
tested in production.
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 500mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 1% (TJ=25oC) or 2% (-
40oC≤TJ≤125oC) below its nominal value measured at 1V differential.
Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.
