Designation of Package Type :
N: SOT-23-5 (Mini mold)
K: PLP1616-6
Setting Output Voltage (VOUT) :
Stepwise setting with a step of 0.1V in the range of 1.2V to 4.0V is possible.
Exceptions 1.25V output type: R1182x121x5, 1.85V output type: R1182x181x5,
2.85V output type: R1182x281x5.
Designation of Mask Option
B: active high, without auto discharge function* at OFF state.
D: active high, with auto discharge function* at OFF state.
Designation of Taping Type :
Ex. TR (refer to Taping Specifications; TR type is the standard direction.)
Designation of composition of pin plating:
-F: Lead free plating (SOT-23-5)
None: Au plating (PLP1616-6)
*) When the mode is into standby with CE signal, auto discharge transistor turns on, and it makes the turn-off
speed faster than normal type.
