Setting Output Voltage (VOUT):

Stepwise setting with a step of 0.6V in the range of 1.5V to 6.0V is possible.

Setting Detector Threshold Voltage (–VDET):

b

Stepwise setting with a step of 0.1V in the range of 1.2V to 5.0V is possible.

Designation of Version Symbols:

c

A: Operation of all the internal circuits is stopped by setting CE pin at VDD level.

B: Operation of only Step-up DC/DC converter is stopped by setting CE pin atVDD level.

Designation of Taping Type:

Ex. 8pin SOP : T1, T2

d

(refer to Taping Specification)

“T2” is prescribed as a standard.

For example, the product with Output Voltage 5.0V, Detector Threshold 4.5V, Version A, and Taping Type T1,

is designated by Part Number RS5RJ5045A-T1.
