LOW-DROPOUT REGULATORS — HIGH EFFICIENCY
Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8188S— voltage regulators offer the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop computers and personal data assistants, these devices deliver a regulated output at up to 250 mA (transient), which is limited only by package power dissipation. Regulated output voltages between 2.5 V and 3.3 V are trimmed at wafer probe. A PMOS pass element provides a typical dropout voltage of only 90 mV at 60 mA of load current.
