CAT6217-330TDGT3

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

The CAT6217-330TDGT3 is a fixed-output 3.3 V CMOS low dropout regulator with a maximum output current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 90 mV at full load. The device provides ±1.0% initial accuracy for outputs ≥ 2.0 V and includes thermal protection, under-voltage lockout, and current limiting. It utilizes a 5-lead TSOT-23 package and requires a 1 μF ceramic output capacitor for stability.

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

What is the purpose of the BYP pin?

The BYP pin allows connection of an optional 10 nF capacitor to ground to reduce output noise and enhance Power Supply Rejection Ratio (PSRR) at high frequencies.

How does the enable pin function?

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