ACE511

Technology

500mA LDO Linear Voltage Regulator

VER 1.2

Electrical Characteristics

Operating Conditions: VIN = 5V, IOUT =10mA; TJ=25 ℃,unless otherwise specified.(COUT=2.2uF, ,CIN=2.2 uF)

Notes:

1. Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range.

2. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load

regulation in the load range from 100μA to 500mA. Changes in output voltage due to heating effects are covered by the

thermal regulation specification.

3. Dropout voltages is defined as the input to output differential at which the output voltage drops 2% below its nominal value

measured at 1V differential.
