The ADP170/ADP171/ADP172 are low voltage input, low quiescent current, low-dropout (LDO) linear regulators that operate from 1.6 V to 3.6 V and provide up to 300 mA of output current. The low 50 mV dropout voltage at 300 mA load improves efficiency and allows operation over a wide input voltage range. The low 23 μA of quiescent current at no load makes the ADP172 ideal for battery-operated portable equipment.

The ADP172 is capable of 31 fixed-output voltage options, ranging from 0.8 V to 3.0 V. The ADP172 is optimized for stable operation with small 1 μF ceramic output capacitors. Ideal for powering digital processors, the ADP172 exhibits good transient perform- ance and occupies minimal board space. Compared with commodity-type LDOs, the ADP172 provides 20 dB to 40 dB better power supply rejection ratio (PSRR) at 100 kHz, making the ADP172 an ideal power source for analog-to-digital converter (ADC) mixed-signal processor systems and allowing use of smaller size bypass capacitors. In addition, low output noise performance without the need for an additional bypass capacitor further reduces printed circuit board (PCB) component count.

Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP172 is available in a tiny 4-ball, 0.5 mm pitch WLCSP for the smallest footprint solution to meet a variety of portable power applications.

Features and Benefits

  • Input voltage range: 1.6 V to 3.6 V 
  • Output current range: 0 mA to 300 mA 
  • Output voltage accuracy: ±1% 
  • Operating temperature range: −40°C to +125°C

Product Detail

The ADP172 evaluation board is used to demonstrate the functionality of the ADP172 series of linear regulators. Simple device measurements such as line and load regulation, dropout voltage, and ground current can be demonstrated with only a single voltage supply, a voltmeter, a current meter, and load resistors.


For more information about the ADP172 linear regulator, see the ADP172 data sheet.
