Linear Voltage Regulator HM6220 Guaranteed 150mA Output and Offered Better than 1% Initial Accuracy
The HM6220 is an efficient linear voltage regulator with an ultralow-noise output, a very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and a very low ground current (600μA at 100mA output). The HM6220 offers better than 1% initial accuracy.
Designed especially for hand-held battery-powered devices, the HM6220 includes a CMOS- or TTL-compatible enable/shutdown control input. When shut down, its power consumption drops nearly to zero. The regulator ground current increases only slightly in a dropout, further prolonging the battery life.
The HM6220 key features are a reference bypass (BYP) pin to improve its already excellent low noise performance, reversed-battery protection, current limiting, and overtemperature shutdown.
The HM6220 is available in fixed (-XX) and adjustable (Adj) output voltage versions in a small SOT-23-5 package.
The fixed output voltage version - HM6220-XX - may have a nominal output voltage (XX) within 1.5V to 12V.
