SA57003 Datasheet | Philips Semiconductors

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 m A. The other two dependent outputs 4, 5 are capable of supplying current up to 185 m A and 195 m A, 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 mon input voltage pin, VIN. The dependent output voltage regulators, VOUT4 and VOUT5 have a mon 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. - No load quiescent current of 170 µA - Maximum input voltage of 12 V - Internal current and thermal limit - Supply voltage rejection: 60 d B (typical) @ f = 1.0 k Hz - Internal trimmed voltage reference SIMPLIFIED SYSTEM DIAGRAM ON/OFF4 VOUT1 ON/OFF5 ON/OFF1 ON/OFF3 ON/OFF2 1 2 3 4 16 15 14 13 VOUT5 VOUT3 5 6 VIN CIN 10 µF 7 8 12 11 10 9 VOUT2 VOUT4 CNS1,2,3 (optional) 0.01 µF CERAMIC COUT1,2,3,4,5 1.0 µF CERAMIC OR TANTALUM SL01421 Figure 1.
