MIC2214-PNBML TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC2214-PNBML TR is a dual µCap low dropout regulator with an open-drain driver and power-on reset circuit. It features two LDO outputs: Output 1 provides 150mA, while Output 2 provides 300mA and includes the POR function. The device operates within an input voltage range of 2.25V to 5.5V. Fixed output voltages are 3.0V for Regulator 1 and 2.85V for Regulator 2. It utilizes a 10-pin 3mm × 3mm MLF™ package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How is the Power-On Reset delay time configured?

The delay time is set by connecting an external capacitor from the SET pin to ground. The internal current source charges this capacitor until it reaches a threshold voltage.

What is the maximum current capability of the open-drain driver?

The open-drain driver (DRV) is capable of sinking up to 150mA of current.
