CAT6219-280MV2T3

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

The CAT6219-280MV2T3 is a 500 mA CMOS low dropout regulator with a fixed 2.80 V output, housed in a WDFN-6 (1.5 mm x 1.5 mm) package. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 300 mV at full load. The device provides ±1.0% initial accuracy for outputs ≥ 2.0 V and includes under voltage lockout, thermal protection, and fold-back current limit. It supports ceramic capacitors for stability and offers a quick-start feature with external bypass capabilities.

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

What is the function of the BYP/ADJ pin?

For the fixed voltage version, the BYP/ADJ pin serves as the reference bypass connection. Connecting a capacitor here reduces output noise and enhances PSRR.

How does the enable pin operate?

The EN pin is active high and includes an internal 2.5 MΩ pull-down resistor. Leaving it open disables the regulator, while driving it high enables the output.
