- ADP2140ACPZ2518R7
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3769766-ADP2140ACPZ2518R7
- Description:
- IC REG DL BCK/LINEAR 10LFCSP
- Datasheet:
- ADP2140ACPZ2518R7
Description
The ADP2140 is a highly efficient, low quiescent current buck converter with a 300 mA LDO regulator. It is packaged in a small 10-lead 3 mm x 3 mm LFCSP. The total solution requires only four tiny external components.
The buck regulator uses a proprietary high-speed current-mode, constant frequency, pulse-width modulation (PWM) control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2140 has a power-saving variable frequency mode to reduce switching frequency under light loads.
The LDO is a low quiescent current, low dropout linear regulator designed to operate in a split supply mode with Vis as low as 1.65 V. The low input voltage minimum allows the LDO to be powered from the output of the buck regulator, increasing efficiency and reducing power dissipation.
The ADP2140 runs from input voltages of 2.3 V to 5.5 V, allowing single Li /Li-polymer Icell, multiple alkaline/NiMH cell, PCMCIA, and other standard power sources.
