TILP5907UVX-3.3/NOPB
Overview
The LP5907UVX-3.3/NOPB is a high-performance linear voltage regulator designed to provide up to 250mA of output current with extremely low noise and high PSRR. It is specifically engineered for RF and analog circuits that require a clean 3.3V supply without the need for an external noise bypass capacitor. This device is housed in a tiny 4-DSBGA package, making it suitable for space-constrained mobile and handheld applications.
Why Choose This Part
This LDO stands out with a very high PSRR of 82dB at 1kHz and a low output noise floor of less than 6.5uVRMS, which eliminates the need for bulky filtering components. It features a low dropout voltage of 120mV at full load and includes an automatic output discharge function to ensure a controlled power-down state.
Applications
Key Specifications
Getting Started
To implement this regulator, place 1uF ceramic capacitors at both the input and output as close to the DSBGA pins as possible. Since the DSBGA package uses a 0.4mm pitch, ensure your PCB manufacturing process can handle micro-vias or thin traces for fan-out. The Enable pin should be pulled high to VIN to activate the device or controlled by a GPIO for power sequencing.
