POWER
(1) Unless otherwise specified, V
(2) Required to maintain regulation. Voltage set resistors R1, R2 are usually utilized for minimum load current.
(3) Current used to drive the output section; minimum value equals the standby current of the device.
(4) V
(5) 30ms.
(6) Over Temp (O.T.) = over specified operating junction temperature range.
(7) Minimum input/output voltage required to maintain 1% regulation.
