Regulator (1.8V product)

Topr=25℃

Detector (2.7V product)

Test conditions: Unless otherwise stated:

DC/DC : VIN=3.6V [@ DCOUT:2.2V]

VR: VIN = 2.8V (VIN=VROUT(T) + 1.0V)

VD: VIN=5.0V

Common conditions for all test items: CE=VIN, MODE=0V

* VROUT(T) : Setting output voltage

NOTE:

*1 : Including VD supply current (VD operates when in stand-by mode.)

*2 : Including hysteresis operating voltage range.

*3 : ON resistance (Ω)= 0.05 (V) / ILX (A)

*4 : EFFI = { ( Output Voltage x Output Current ) / ( Input Voltage x Input Current) } x 100

*5 : Time until it short-circuits DCOUT with GND through 1Ωof resistance from a state of operation and is set to DCOUT=0V

from current limit pulse generating.

*6 : Vdif = (VIN1

(*7) - VROUT1 (*8) )

*7 : VIN 1 = The input voltage when VROUT1 appears as input voltage is gradually decreased.

*8 : VROUT1 = A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VROUT(T) + 1.0V} is input.

*9 : Current limit = When VIN is low, limit current may not be reached because of voltage falls caused by ON resistance or

serial resistance of coils.

*10: Integral latch circuit=latch time may become longer and latch operation may not work when VIN is 3.0V or more.

*11: VDR(E) = VD release voltage

*12: When temperature is high, a current of approximately 5.0μA (maximum) may leak.
