AP131
300mA Low Dropout Linear Regulator with Shutdown
Features
General Descriptions
- Input voltage range is up to 7V
The AP131 is a 300mA, fixed output voltage, low
dropout linear regulator. The Device included pass
element, error amplifier, band-gap, current limit and
thermal shutdown circuitry. The device is ON when
EN pin is set to logic high level.
- Dropout voltage 400mV at 300mA output current
- Guaranteed 300mA output current.
- Internal Ron =1.5Ω PMOS draws no base current
- Low quiescent current 50µA
- Output voltage 2% accuracy, and 1.5V to 5V with
0.1V step
The characteristics of low dropout voltage and less
quiescent current make it good for some critical
current application, for example, some battery
powered devices. The typical quiescent current is
approximately 50µA from zero to maximum load.
Due to internal flexible design, result in extensively
fixed output voltage versions and make it
convenient to use for applications. Built-in
current-limit and thermal-shutdown functions
prevent any fault condition from IC damage. An
external capacitor can be connected to the BP pin
and reduce the output noise.
- Active low shutdown function (EN pin).
- Fast transient response
- Good load regulation
- Current limit and thermal shutdown protection
- Short circuit current fold-back
- SOT89-5L and SOT23-5L packages
Applications
- Wireless Communication
- Battery Powered device
- CD-ROM, DVD, and LAN Card
- PC peripheral

Note 1. Dropout voltage is defined as the input to output differential voltage. Dropout is measured at constant junction temperature by
using pulsed ON time, and the criterion is VOUT inside target value ±2%. This test is skipped at the condition of VIN<3V.
Note 2. Current limit is measured at constant junction temperature by using pulsed testing with a low ON time.
Note 3. Regulation is measured at constant junction temperature by using pulsed testing with a low ON time.
Note 4. Guaranteed by design.
