Overview

The TPS7A2015PDBVR is a 300mA low-dropout (LDO) linear regulator that provides a fixed 1.5V output from an input range of 1.6V to 6.0V. It is engineered for sensitive analog circuitry, featuring ultra-low output noise of 7uVrms and a high PSRR of 65dB at 1kHz. With a very low quiescent current of only 6.5uA, it is optimized for extending battery life in portable electronics.

Why Choose This Part

This regulator eliminates the need for an external noise-bypass capacitor, saving PCB space and reducing BOM cost. It features a smart enable pulldown to prevent floating states and is stable with a tiny 1uF ceramic output capacitor. Additionally, it offers robust protection including over-temperature, over-current, and under-voltage lockout (UVLO).

Applications

Smartphones and Tablets
Provides clean power to noise-sensitive RF and audio components while maintaining high efficiency during standby.
IP Network Cameras
Regulates power for image sensors where low noise is critical for maintaining image clarity.
Wearable Electronics
The small SOT-23 package and 6.5uA Iq make it ideal for space-constrained, battery-operated devices.
Smart Meters
Ensures stable voltage for communication modules and microcontrollers in long-term field deployments.

Getting Started

To evaluate this part, ensure the input and output ceramic capacitors are placed as close to the SOT-23 pins as possible to minimize parasitic inductance. The EN pin can be tied to VIN for always-on operation or driven by a GPIO for power sequencing. Thermal performance should be verified using the PCB copper area as the primary heat sink for the 300mA load.
