When measuring output ripple, it is recommended that an external 22 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. Operation at no-load will not damage these units. However, they may not meet all specifications. 4. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating. 3.3 5.0 3.3 5.0 Current Current (mA, Max) (mA, Min) 2,000 2,000 2,000 2,000 Efficiency (%, Typ) Fuse Rating Slow-Blow (mA) 92 93 83 85 4,000 3,000 1,000 1,000 200 200 200 200 Derating Curve Remote ON/OFF (Optional, see below) Parameter Min Max Units Supply On 3.0 5.0 or Open VDC Supply Off -0.3 1.2 VDC Standby Input Current 300 µA Control Input Current (On) 50 µA -100 µA Control Input Current (Off) Control Common Output Trim Connection Referenced to Neg. Input Remote ON/OFF Notes: 1. Maximum sink current at the on/off terminal (Pin 1) during a logic low is 100 µA. 2. Maximum allowable leakage current of a switch connected to the on/off terminal (Pin 1) at logic high (3.0V to 5.0V) is 50 µA. Mechanical Dimensions The output voltage of the SR1000W may be trimmed down by connecting an external resistor between the +Vout (pin 4) and Output Trim (pin 5). This resistor value (in Ω) is given by: Vout Trim = (Rx • 1200) • (Vout - 1.195) (Rx • 1.195) - (1200 • (Vout - 1.195)) For the SR1001W & SR1021W; Rx = 2,130Ω (Vout = 1.8 to 3.3VDC For the SR1011W & SR1022W; Rx = 3,840Ω (Vout = 3.0 to 5.0VDC Pin Connections Pin 1 2 3 4 5 Description Remote On/Off +Vin -Vin (Gnd) +Vout Output Trim Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.01 (±0.25) MicroPower Direct www.micropowerdirect.com 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected]
