TYPICAL PERFORMANCE CHARACTERISTICS

COUT Auto-Discharge Function

LR6200B series can discharge the electric charge in the output capacitor (COUT), when a

low signal to the CE pin, which enables a whole IC circuit turn off, is inputted via the

N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM).

The COUT auto-discharge resistance value is set at 80 (VOUT=3.0V @ VIN=5.0V at typical).

The discharge time of the output capacitor (COUT) is set by the COUT auto-discharge

resistance (R) and the output capacitor (COUT). By setting time constant of a COUT

auto-discharge resistance value [RDISCHRG] and an output capacitor value (COUT) as

x RDISCHRG), the output voltage after discharge via the N-channel transistor is calculated by

the following formulas.

( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time,

: COUT auto-discharge resistance RDISCHRG×Output capacitor (COUT) value C)
