TPS728185315YZUR TI LDO Regulator | 5-DSBGA | 1.85V/3.15V Output, 200mA

Product Overview

The TPS728185315YZUR from Texas Instruments is a dual-output, low-dropout (LDO) linear regulator designed for space-constrained applications. Housed in a compact 5-pin DSBGA package (0.9mm x 1.3mm), it provides two independent regulated outputs: 1.85V and 3.15V, each capable of delivering up to 200mA. With a low dropout voltage of typically 130mV at full load and a quiescent current of only 55µA, this device is ideal for battery-powered and portable electronics where efficiency and small footprint are critical.

Detailed Technical Specifications

Key Features

• Dual independent LDO outputs with fixed voltages (1.85V and 3.15V)
• Low dropout voltage: 130mV typical at 200mA load
• Ultra-low quiescent current: 55µA per channel
• High PSRR: 60dB at 1kHz for clean power delivery
• Low output noise: 30µVrms ideal for noise-sensitive circuits
