产品详情和应用
The ADPL42010A is a low dropout regulator optimized for fast transient response. The device is capable of supplying 1A of output current with a dropout voltage of 400mV. Operating quiescent current is 1mA, dropping to <1μA in shutdown.
Output voltage range is from 1.21V to 20V. The ADPL42010A regulator is stable with output capacitors as low as 10μF. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The ADPL42010A is available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V, and as an adjustable device with a 1.21V reference voltage. The ADPL42010A regulator is available in 3-lead SOT-223 and 8-lead SO packages.
APPLICATIONS
- 3.3V to 2.5V Logic Power Supplies
- Post Regulator for Switching Supplies
