Datasheet Summary
LOW-DROPOUT, 3.3 V REGULATOR
- HIGH EFFICIENCY
Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8187SLT voltage regulator offers the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop puters and personal data assistants, the device delivers a regulated, continuous 3.3 V output at up to 75 mA under normal operating conditions, or to 150 mA (transient) under worst-case conditions. A PMOS pass element provides a typical dropout voltage of only 85 mV at 60 mA of load current. The low dropout voltage permits deeper battery discharge...
