TPS7A1418PDRVR

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

The TPS7A14PDRVR is a low-input, ultra-low dropout linear regulator (LDO) from Texas Instruments designed for high-efficiency power delivery in battery-powered systems. It supports an input voltage range of 0.7 V to 2.2 V and provides fixed output voltages between 0.5 V and 2.0 V with 1% accuracy over load, line, and temperature variations. The device delivers up to 1 A of output current while maintaining excellent transient response and high power-supply rejection ratios. It utilizes a separate BIAS pin to power internal circuitry, enabling operation at very low VIN-VOUT differentials.

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

Verify the specific package variant against the datasheet orderable addendum, as the DRV suffix denotes a 6-pin WSON package. Confirm that the required output capacitance meets stability requirements, typically 2.2 µF or greater ceramic capacitors. Ensure the BIAS pin supply voltage adheres to recommended operating conditions to maintain specified electrical characteristics.

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

Select this component when system architecture requires powering the main power path from a pre-regulated low-voltage source while using a higher voltage rail for internal biasing. It is suitable for applications demanding tight output voltage accuracy and fast recovery from load transients. Consider the thermal resistance metrics if operating near maximum current limits in confined PCB spaces.

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

This part belongs to the TPS7A14 family of ultra-low dropout regulators. The DRV suffix indicates the 6-pin WSON package format, which measures 2 mm by 2 mm. This family is engineered specifically for portable electronics where maximizing battery life through high efficiency at low voltage drops is critical.

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

Check the TPS7A14YBK variant if a smaller 6-bump WCSP package is required instead of the WSON form factor. Verify compatibility with existing PCB footprints and thermal pad connections when substituting within the same family.
