Overview
The TLV70033 is a 200mA low-dropout (LDO) linear regulator that provides a fixed 3.3V output from an input range of 2V to 5.5V. It is designed for portable, battery-powered applications where low quiescent current and small PCB footprint are critical requirements.
Why Choose This Part
The device features a high PSRR of 68dB at 1kHz to filter supply noise and an ultra-low quiescent current of 31uA, which extends battery life. It is stable with very small 0.1uF ceramic output capacitors, reducing the overall bill of materials and board space.
Applications
Portable Handheld Devices
Ideal for smartphones and tablets due to its high PSRR and small SC70 and SOT-23 packages.
Precision Analog Power
Powers sensitive analog-to-digital converters and sensors that require low-noise rails.
Wireless Modules
Provides stable 3.3V power to Zigbee or Bluetooth Low Energy modules with minimal external capacitance.

Getting Started
To use this LDO, place a 0.1uF ceramic capacitor close to the VIN and VOUT pins. The EN pin must be driven high to enable the regulator; if power sequencing is not required, it can be tied directly to VIN.
