CAT6219ADJVP5GT4

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

The CAT6219ADJVP5GT4 is a 500 mA CMOS low dropout regulator in a TDFN-6 package. It operates with input voltages from 2.3 V to 5.5 V and features an adjustable output voltage. The device provides fast response time, quick-start functionality, and zero shutdown current. Key electrical characteristics include a typical dropout voltage of 300 mV at 500 mA, ±1.0% initial accuracy for outputs ≥ 2.0 V, and a typical ground current of 55 µA at no-load. It includes under voltage lockout, thermal protection, and fold-back current limit.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix VP5 corresponds to the TDFN-6 package configuration as documented in the ordering information table. Confirm that the ADJ designation indicates the adjustable output variant rather than a fixed voltage option. Ensure compatibility with the required operating temperature range and input voltage specifications for the target application design.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when an adjustable output voltage is required within the 2.3 V to 5.5 V input range. Consider the TDFN-6 package for space-constrained designs requiring a low profile. Evaluate the need for the quick-start feature if external noise reduction capacitors are utilized. Verify that the load current requirements do not exceed the guaranteed 500 mA peak output current rating.
