SE1122 SEAWARD [Seaward Electronics Inc.], SE1122 Datasheet - Page 2

• Manufacturer Part Number: SE1122
• Description: 1A Low Dropout Positive Regulator
• Manufacturer: SEAWARD [Seaward Electronics Inc.]

Absolute Maximum Rating
Electrical Characteristic
V
Notes:
1. Low duty cycle pulse testing with which T
3. The dropout voltage is the input/output differential at which the circuit ceases to regulate against further
reduction in input voltage. It is measured when the output voltage has dropped 2% from the nominal value
obtained at V
