Overview

  • Maximum output current: 300 mA
  • Input voltage range: 2.5 V to 5.5 V
  • Light load efficient IGND = 75 μA with 100 μA load
  • Low shutdown current: <1 μA
  • Very low dropout voltage: 170 mV @ 300 mA load
  • Initial accuracy: ±1%
  • Accuracy over line, load, and temperature: ±2%
  • See datasheet for additional features

The ADP1712 / ADP1713 / ADP1714, available in a tiny, 5-lead TSOT package, are low dropout linear regulators that operate from 2.5 V to 5.5 V and provide up to 300 mA of output current. The low 170 mV dropout voltage at a 300 mA load improves efficiency and allows operation over a wide input voltage range. Using a novel scaling architecture, ground current is a very low 75 μA when driving a 100 μA load, making the ADP1712 / ADP1713 / ADP1714 ideal for battery-operated portable equipment.

The ADP1712 / ADP1713 / ADP1714 are available in 16 fixed output voltage options. The ADP1712 is also available in an adjustable version, which allows output voltages that range from 0.8 V to 5 V via an external divider. The ADP1712 fixed version allows an external capacitor to be connected to program the soft-start time. The ADP1713 allows a reference bypass capacitor to be connected, which reduces output voltage noise and improves power supply rejection. The ADP1714 includes a tracking feature, which allows the output to follow an external voltage rail or reference.

The ADP1712 / ADP1713 / ADP1714 are optimized for stable operation with small 2.2 μF ceramic output capacitors, allowing good transient performance while occupying minimal board space. An enable pin controls the output voltage on all devices, and an undervoltage lockout circuit disables the regulator if IN drops below a minimum threshold. The parts also have short circuit protection and thermal overload protection, which prevent damage to the devices in adverse conditions.
