S witc h-Mode Regulator with
+5V to ±12V or ±15V Dual Output
_______________________________________________________________________________________

Note 1:
Devices are 100% tested to these limits under 0mA to 100mA and to 125mA conditions using automatic test equipment.
The ability to drive loads up to 1A is guaranteed by the current-limit threshold, output swing, and the output current
source/sink tests. See Figures 2 and 3.
Note 2:
Actual load capability of the circuit of Figure 2 is ±200mA in ±15V mode and ±250mA in ±12V mode. Load regulation is
tested at lower limits due to test equipment limitations.
Note 3:
Guaranteed by design.
Note 4:
Measured at Point A, circuit of Figure 2, with PDRV disconnected.
