AP2138/2139

ULTRA LOW QUIESCENT CURRENT CMOS LDO

Description

Features

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.



Ultra-Low Quiescent Current: 1.0µA Typical

Output Voltages: 1.2V, 1.4V, 1.5V, 1.8V, 2.1V, 2.2V, 2.5V, 2.8V,

3.0V, 3.3V, 3.6V and 4.0V



High Output Voltage Accuracy: ±2%

Output Current: 250mA

The difference between AP2138 and AP2139 is the AP2139 has an

enable circuit with a quick discharge function.

Low Dropout Voltage:

25mV Typical at I_OUT= 10mA and V_OUT= 3V

200mV Typical at I_OUT= 100mA and V_OUT= 3V

These ICs feature high output voltage accuracy, extremely low

quiescent current and low dropout voltage which make them ideal for

use in various power sources for portable applications.



Line Regulation: 6mV Typical

Load Regulation: 25mV Typical

Low Output Voltage Temperature Coefficient: ±100ppm/°C

Low Standby Current: 0.1µA Typical (AP2139)

Active Quick Output Discharge (AP2139)

Logic-Controlled Enable (AP2139)

The AP2138/2139 series have 1.2V, 1.4V, 1.5V, 1.8V, 2.1V, 2.2V,

2.5V, 2.8V, 3.0V, 3.3V, 3.6V and 4.0V fixed output voltage versions.

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

The AP2138 series is available in SOT-23-3 and SOT-89 packages,

AP2139 series is available in SOT-23-5 package.

Applications



Battery Powered Equipment

Reference Voltage Sources

Cameras, Video Cameras

Portable AV Systems

Mobile Phones

Communication Tools

Portable Games

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.

2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and

Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
