SPX5205 SPX5205 150 mA, Low-Noise LDO Voltage Regulator (Preliminary Information) FEATURES Low Noise Output LDO 1% Initial Accuracy At 150mA Very Low Quiescent Current Low Dropout Voltage (210mV At 150mA) 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 Zero Off-Mode Current Small 5-Pin SOT-23 Pin Compatible to MIC5205/MAX8877 (Fixed Option Only) 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 SPX5205 is an excellent choice for use in battery-powered applications, and where power conservation is desired. Such as: cellular/ cordless telephones, radio control systems, and portable computers. This device is a positive voltage regulator with very low dropout voltage and low output noise. It uses very little quiescent current of 750 µA at 100 mA output load. VOUT tolerance is less than 1% with a compensated temperature coefficient. Many fixed output voltages, as listed below, or an adjustable version are available in a small 5-pin SOT-23 package. Other key features include: Zero off-mode current, protection against reversed battery, thermal and current limiting.
