Linear voltage regulator

4 June 2014 Power Electronics / Power Management

STMicroelectronics’ LDLN015 is an ultra low-noise linear regulator which provides 150 mA maximum current from an input voltage between 2,1 V and 5,5 V, with a typical dropout voltage of 86 mV. With its 6,3 VRMS noise value in a band from 10 Hz to 100 kHz, the device provides a very clean output suitable for highly sensitive loads.

The IC is stable with ceramic capacitors and its high power supply rejection ratio, low quiescent current and very low noise make it suitable for energy conscious battery powered applications. Power supply rejection is higher than 90 dB at low frequencies and starts to roll off at 10 kHz.

An enable logic control function puts the LDLN015 into shutdown mode with total current consumption below 1 A. The device also includes short-circuit constant current limiting and thermal protection.
