INTEGRATED CIRCUITS SA57003 Five-output composite voltage regulator Product data Supersedes data of 2001 Aug 01 2003 Oct 13 Philips Semiconductors Philips Semiconductors Product data Five-output composite voltage regulator SA57003 GENERAL DESCRIPTION The SA57003 is a very low noise, low dropout voltage regulator with three independent preset outputs from 2.0 V to 5.0 V and two dependent outputs regulated from 2.82 V up to VOUT3. The output current is the same for all three independent outputs 1, 2, 3 and each output is capable of supplying 200 mA. The other two dependent outputs 4, 5 are capable of supplying current up to 185 mA and 195 mA, respectively. Additionally, the SA57003 has an independent ON/OFF input pin for each output to allow individual subcircuits to be turned off when not needed, making the device very useful for applications where power conservation is important. The independent output voltage regulators VOUT1, VOUT2, and VOUT3 have a common input voltage pin, VIN. The dependent output voltage regulators, VOUT4 and VOUT5 have a common input voltage pin, VOUT3. The SA57003 regulator is offered in the TSSOP16 package. FEATURES VOUT tolerance ±3% over temperature range –40 °C to +85 °C ON/OFF input pin (logic-controlled shut-down) for each output Very low dropout voltage (0.15 V typical for Outputs 1, 2, 3 and 0.25 V for Outputs 4, 5) APPLICATIONS Mobile phones Video cameras Portable battery-powered telemetry equipment.
