The ADP220 with a 200mA dual output is in one
Voltage regulatorThe combination of high PSRR (Power Supply Rejection Ratio), low noise, low quiescent current, and low dropout voltage makes it ideal for wireless applications with demanding performance and board space constraints. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP220 extend battery life in portable devices. At operating frequencies up to 100KHz,
ADP220Very low voltage headroom and higher than 60dB power supply rejection can be achieved. The ADP220 offers lower noise characteristics than competing LDOs without the need for noise bypass capacitors. The ADP221 contains an active pull-down circuit to rapidly discharge the output load.
The ADP220 is available in a miniature 6-ball WLCSP package that requires only a very small 1uF ± 30% ceramic output capacitor for stable operation, enabling a wide range of mobile power supplies with minimal board area. The ADP220 offers multiple output voltage combinations, from 0.8V to 3.3V, and provides overcurrent and thermal protection against damage in these conditions.
