4 / 5 page Dual 150mA ULTRA LOW DROPOUT, LOW NOISE REGULATOR © 2000 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 SC1456 PRELIMINARY - June 15, 2000 4 BLOCK DIAGRAM PIN CONFIGURATION Top View MSOP-10 PIN DESCRIPTIONS Pin # Pin Name Description 1 EN1 Active high enable pin for device 1. Connect to VIN1 if not being used. 2 GND Ground pin. Can be used for heatsinking if needed. Electrically connected to pin 7. 3 SET1 Connecting this pin to ground results in the internally preset value for V OUT1. Connecting to an external resistor divider changes V OUT1 to: 4 OUT2 Regulator output for device 2, sourcing up to 150mA 5 IN2 Supply input pin for device 2. 6 EN2 Active high enable pin for device 2. Connect to VIN2 if not being used. 7 GND Ground pin. Can be used for heatsinking if needed. Electrically connected to pin 2. 8 SET2 Connecting this pin to ground results in the internally preset value for V OUT2. Connecting to an external resistor divider changes V OUT2 to: 9 OUT1 Regulator output for device 1, sourcing up to 150mA 10 IN1 Supply input pin for device 1. + • = 2 R 1 R 1 250 . 1 V 1 OUT + • = 2 R 1 R 1 250 . 1 V 2 OUT VOLTAGE OPTIONS Replace X in the part number (SC1456XIMS) by the letter shown below for the corresponding voltage option: XV OUTA (V) V OUTB (V) A2.5 2.5 B2.8 2.8 C3.0 3.0 D3.3 3.3 |
