ULTRA LOW QUIESCENT CURRENT CMOS LDO
General Description
Features
Data Sheet
AP2138/2139
The AP2138/2139 series are CMOS-based positive
voltage regulator ICs. Each of these ICs consists of a
voltage reference, an error amplifier, a resistor network
for setting output voltage and a current limit circuit for
current protection.
The difference between AP2138 and AP2139 is the
AP2139 has an enable circuit with a quick discharge
function.
These ICs feature high output voltage accuracy,
extremely low quiescent current and low dropout volt-
age which make them ideal for use in various power
sources for portable applications.
The AP2138/2139 series have 1.2V, 1.4V, 1.5V, 1.8V,
2.5V, 2.8V, 3.0V, 3.3V, 3.6V and 4.0V fixed output
voltage versions.
The AP2138 series is available in SOT-23-3 and SOT-
89 packages, AP2139 series is available in SOT-23-5
package.
