® STV8130AD ADJUSTABLE AND +3.3 V DUAL VOLTAGE REGULATOR WITH DISABLE AND RESET FUNCTIONS PRELIMINARY DATA FEATURES s Input Voltage Range: 5 V to 18 V s Output Currents up to 750 mA s Fixed Precision Output 1 Voltage: 3.3 V ±2% s Adjustable Output 2 Voltage: 2.8 to 16 V s Output 1 with Reset Function s Output 2 with Disable Function by TTL Input s Short-circuit Protection at both Outputs s Thermal Protection s Low Dropout Voltage SIP9 (Plastic Package) ORDER CODE: STV8130A# DESCRIPTION The STV8130A# and STV8130D# are monolithic dual positive voltage regulators designed to provide a fixed precision output voltage of 3.3 V and an adjustable voltage between 2.8 and 16 V for currents up to 750 mA. An internal reset circuit generates a reset pulse when the voltage of Output 1 drops below the regulated voltage value. Output 2 can be disabled via the TTL input. Short-circuit and thermal protections are included.
