Designation of Package Type:

RP101Kxx1x-xx: PLP1612-4 (t=0.6mm)

RP101Kxx2x-xx: PLP1612-4B (t=0.4mm)

RP101Nxx1x-xx: SOT-23-5

Setting Output Voltage (VOUT):

The following 16 kinds of voltage are standard.

1.2V, 1.3V, 1.5V, 1.8V, 1.85V, 1.9V, 2.0V, 2.1V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V,

3.0V, 3.1V, 3.3V

Exceptions:1.85V=RP101x18xx5-xx-x, 2.85V=RP101x28xx5-xx-x

Designation of Mask Option

B: active high, without auto discharge function* at OFF state.

D: active high, with auto discharge function* at OFF state.

d

Designation of Taping Type:

Ex. TR (refer to Taping Specifications; TR type is the standard direction.)

Designation of composition of pin plating:

e

-F: Lead free plating (SOT-23-5)

None: Au plating (PLP1612-4, PLP1612-4B)

*) 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.
