TPS77601DG4

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

The TPS77601DG4 is a fast transient response, 500mA low-dropout voltage regulator from the TPS776xx family. It features an adjustable output voltage range of 1.2V to 5.5V and operates with an input voltage between 2.7V and 10V. The device delivers a typical quiescent current of 85µA and achieves a dropout voltage of 169mV at full load. It includes an open-drain Power Good (PG) output with a 200ms delay. The component is housed in an 8-pin SOIC package and supports operation across a junction temperature range of -40°C to +125°C.

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

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm material composition, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required thermal performance and packaging quantity for the intended production volume.

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

Select this regulator for applications requiring high efficiency under varying loads due to its voltage-driven PMOS architecture. Ensure the output capacitor meets the specified equivalent series resistance requirements to maintain loop stability. Consider the thermal dissipation limits when designing for high input-to-output voltage differentials at maximum current.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the TPS775xx/TPS776xx family of low-dropout regulators. While the TPS775xx variants include a Reset output, the TPS776xx series specifically integrates a Power Good signal. Both families share identical electrical characteristics regarding current handling, dropout voltage, and transient response performance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional equivalents within the same package include the TPS77601DR and TPS77601DRCR. Verify that any substitute maintains the 8-pin SOIC footprint and compatible thermal resistance values.
