TPS7A1510PDRVR

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

The TPS7A1510PDRVR is a 400-mA low-input, ultra-low dropout linear regulator from Texas Instruments. It operates with 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 in 25-mV steps. The device utilizes an external BIAS pin (2.2 V to 5.5 V) to power internal circuitry, enabling high efficiency at very low VIN-VOUT differentials. It features excellent load transient response, high PSRR, and active output discharge for rapid shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low dropout operation allows efficient regulation with minimal input-to-output voltage difference.
• External BIAS pin enables stable performance when the main input voltage is extremely close to the output voltage.
• Active pulldown circuit rapidly discharges the output capacitor upon disablement.
• Integrated foldback current limit and thermal shutdown protect against overload conditions.

• Wireless headphones and earbuds
• Smart watches and fitness trackers
• Portable medical devices

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

Verify the specific suffix 'DRV' corresponds to the 6-pin WSON package variant as indicated in the datasheet. Confirm the fixed output voltage code matches the required nominal voltage within the 0.5 V to 2.0 V range. Ensure the component revision aligns with the latest production data release. Cross-reference the orderable addendum for exact packaging and availability details before finalizing procurement.

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

Select this regulator for applications requiring high efficiency at very low voltage differentials. The external BIAS pin must be supplied with a voltage greater than or equal to the output plus 1.4 V, or 2.2 V, whichever is higher. Ensure input and output capacitors meet the minimum stability requirements specified in the electrical characteristics. Consider the DRV package's thermal resistance if operating near maximum current limits.

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

This component belongs to the TPS7A15 family of ultra-low dropout regulators designed for battery-powered portable electronics. The family offers various fixed output voltages and package options, including WCSP and WSON. The TPS7A15 series is optimized for applications where space is limited and high efficiency at low voltages is critical, such as in mobile and wearable devices.

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

Check for other TPS7A15 variants with different fixed output voltages or package types (YCK vs DRV). Verify that any substitute maintains the same 400-mA current rating and low-dropout specifications. Ensure the replacement part supports the required BIAS voltage range and has compatible pin configurations.
