ST619LBDR Description

Short technical summary and product information.

The ST619LBDR is a regulated 5V charge pump DC-DC converter from STMicroelectronics, suitable for battery-powered applications requiring low noise. It delivers a stable 5V output with a guaranteed current of 30mA at input voltages of 3V or higher, and 20mA at 2V or higher.

 

This device operates with an input voltage range of 2V to 3.6V and features a low operating supply current of typically 200µA. In shut-down mode, the supply current drops to a maximum of 1µA, with the load disconnected from the input. The charge pump topology eliminates the need for inductors, resulting in very low EMI noise.

 

The ST619LBDR is available in an 8-SOIC package and requires only four external capacitors for operation. Its compact design and low power consumption make it ideal for portable and battery-operated devices where space and energy efficiency are critical.

 

Key electrical characteristics include a fixed 5V output, a step-up topology, and a typical operating frequency of 500kHz. The operating temperature range is -40°C to 85°C (TJ).
