FEATURES
● Output voltage : 2.0 V to 12.0 V, selectable in 0.1 V step● Low equivalent series resistance capacitor : Ceramic capacitor of 0.1 µF or more can be used as the I/O capacitor.
● Input voltage : 3.0 V to 50 V
● High-accuracy output voltage : ±1.0% (at Tj = +25°C), ±3.0% (Tj = −40°C to +105°C)
● Low current consumption : During operation: 4.0 µA typ., 9.0 µA max. (Tj = −40°C to +105°C) During shutdown: 0.1 µA typ., 1.0 µA max. (Tj = −40°C to +105°C)
● Output current : 200 mA (at VIN ≥ VOUT(S) + 2.0 V)*1
● Built-in overcurrent protector : limits overcurrent of output transistor
● Operation temperature range : −40°C to +105°C (S-1142xxxH only)
● Built-in thermal shutdown circuit : prevents damage caused by heat
● Built-in power on/off circuit : longer battery life
● Small package : HSOP-6
● Lead-free product *1. Attention should be paid to the power dissipation of the package when the output current is large.
APPLICATIONS
