Overview

A group of low -dropout (LDO) voltage regulators offering the benefits of wide input voltage range from 1.2V to 5.5V, low dropout voltage, low power consumption, and miniaturized packaging. Quiescent current of only 10μA makes these devices ideal for powering the battery-powered, always-on systems that require very little idle-state power dissipation to a longer service life. There is an option of shutdown mode by selecting the parts with the EN pin and pulling it low. The shutdown current in this mode goes down to only 10nA (typical). These linear regulators are stable with the ceramic output capacitor over its wide input range from 1.2V to 5.5V and the entire range of output load current (0mA to 600mA).

Questions about AP2112K-3.3TRG1

What are the fundamental input voltage and output current specifications of the AP2112K-3.3TRG1?

The TECH PUBLIC AP2112K-3.3TRG1 is a fixed-output low-dropout (LDO) linear voltage regulator with a regulated 3.3V output. It operates from an input voltage range of 1.2V to 5.5V and can supply up to 600mA of continuous output current, making it suitable for powering low-voltage electronic circuits.

How does the AP2112K-3.3TRG1 help improve power efficiency?

The AP2112K-3.3TRG1 features a typical dropout voltage of 320mV at a 600mA load (3.3V output version), helping maintain regulation with minimal voltage loss. It also has a typical ground current of 10µA and a typical shutdown current of 10nA when disabled, contributing to low power consumption.

What power management features are integrated into the AP2112K-3.3TRG1?

The AP2112K-3.3TRG1 includes an Enable (EN) input for on/off control. Pulling the EN pin low places the regulator into shutdown mode to reduce power consumption. The device also provides an integrated output discharge function that discharges the output through an internal resistor when the regulator is disabled.

What protection features and operating conditions does the AP2112K-3.3TRG1 provide?

The AP2112K-3.3TRG1 incorporates current limit protection and thermal shutdown to help protect the device during abnormal operating conditions. It supports an operating temperature range of −40°C to +85°C and provides ±2% output voltage accuracy under specified operating conditions.

What package and capacitor types are supported by the AP2112K-3.3TRG1?

The AP2112K-3.3TRG1 is available in a 5-pin SOT-23-5 surface-mount package. It is designed for use with ceramic or tantalum capacitors and should be used according to the recommended application circuit.
