UNISONIC TECHNOLOGIES CO., LTD 82XX Preliminary LINEAR INTEGRATED CIRCUIT MONOLITHIC IC 82XX SERIES  DESCRIPTION The normal operation of the UTC 82XX is that while the power is turned on or interrupted, detect power supply voltage and then reset the system accurately. The internal circuits of the UTC 82XX include a built-in fixed delay time generating circuit. With a counter timer using an analog/digital hybrid circuit, the UTC 82XX as new low reset type system reset ICs expands the delay.

LOW-DROPOUT REGULATORS

8220 THRU 8233 PRELIMINARY INFORMATION (subject to change without notice) January 18, 2000 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 A8220SLH thru A8233SLH 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 100 mA (transient), which is limited only by package power dissipation. Regulated output voltages of 2.6, 2.7, 2.8, 2.9, 3.0 and 3.3 are currently provided. Other voltages, down to 2.0 volts, are available on special order. A PMOS pass element provides a typical dropout voltage of only 125 mV at 50 mA of load current. The low dropout voltage permits deeper battery discharge before output regulation is lost. Quiescent current does not increase significantly as the dropout voltage is approached, an ideal feature in standby/resume power systems where data integrity is crucial. Regulator accuracy and excellent temperature characteristics are provided by a bandgap reference. The A8220SLH thru A8233SLH include ENABLE inputs to give the designer complete control over power up, standby, or power down. These devices are supplied in a thermally enhanced 5-lead smalloutline plastic package similar to the SOT-23, and fitting the SC-74A footprint. All devices are rated f.
