ST1PS02BQTR General Description

What sets the ST1PS02 apart is its customizable output voltage, which can be easily set using three digital control inputs. This flexibility allows for precise adjustment of the output voltage, ranging from 1.0 V to 3.3 V, to meet the specific requirements of your application. The ST1PS02 achieves remarkable efficiency levels with its enhanced PCC (peak current control) technology, requiring only a 2.2 µH inductor and two small capacitors for optimal performance

Key Features

The device features a high PSRR of -80dB at 100Hz
and a low noise density of 0.2µV/√Hz at 10kHz
It has a temperature range of -40°C to 125°C
