STMicroelectronics LDK320

The LDK320 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 18 V, with a typical dropout voltage of 100 mV. It is stabilized with a ceramic capacitor on the output.

The very good dynamic characteristic, combined with low drop voltage and low quiescent current make it suitable for low power battery-powered applications.

The enable logic control function allows the LDK320 to be in shutdown mode by consuming a total current lower than 1 μA.

This device also includes a short-circuit current limiting, thermal and SOA protections.

Features

• Input voltage from 2.5 to 18 V
• Very low-dropout voltage (100 mV typ. @ 100 mA load)
• Low quiescent current (typ. 60 μA, 1 μA in off mode)
• High PSRR: 88 dB@120 Hz
• Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable
• Logic-controlled electronic shutdown
• Compatible with ceramic capacitor C_OUT = 1 μF
