SPX8863

SPX8863 120 mA, Low Dropout Voltage Regulator (Preliminary Information) FEATURES Low Noise Output LDO 1% Initial Accuracy At 120mA Very Low Quiescent Current Low Dropout Voltage Current & Thermal Limiting Reverse-Battery Protection Wide Range of Fix Output Voltages 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V, 4.5V, 5.0V, & ADJ Zero Off-Mode Current Small 5-Pin SOT-23 Pin Compatible to MAX8863 APPLICATIONS PDA Battery Powered Systems Cellular Phone Cordless Telephones Radio Control Systems Portable/Palm Top/Notebook Computers Portable Consumer Equipment Portable Instrumentation Bar Code Scanners SMPS Post-Regulator PRODUCT DESCRIPTION The SPX8863 is a low-power positive voltage regulator with ultra low noise output and very low dropout voltage. In addition, this device offers very low quiescent current of approximately 600uA at 100mA output. The SPX8863 initial tolerance is less than 1% max and has a logic compatible ON/OFF switching input. The unique features of the SPX8863 include a reference bypass pin for the best performance results of low noise. This device is an excellent choice for use in battery powered applications such as cellular/ cordless telephones, radio control systems, and portable computers. When disabled power consumption drops to nearly zero. The device also has a very low output temperature coefficient, making it a low power voltage reference. The SPX8863 key features include protection against reversed battery, fold-back c...
