Regulator ICs
(2) Pull-down of VP–P
BP5310
The OFF output is pulled down through an effective resistance of 30kΩ.
(3) The module has a built-in short-circuit protection
circuit. Short-circuiting is assumed if the output voltage
does not reach 4.2V (typical) in 40ms (typical), and the
protection circuit starts to operate. When setting the out-
FExternal dimensions (Units: mm)
put capacitor, we recommend considering the capaci-
tance within the IC card and making the output voltage
to reach 8V or more in less than 20ms.
