The S-817 Series is a 3-terminal positive voltage regulator, developed using CMOS technology. Small ceramic
capacitors can be used as the output capacitor, and the S-817 series provides stable operation with low loads
down to 1 µA.
Compared with the conventional voltage regulator, it is of low current consumption, and with a lineup of the
super small package (SNT-4A:1.2 x 1.6mm). It is optimal as a power su pply of small portable device.
Features
• Ultra-low current consumption: Operating current: Typ. 1.2 μA, Max. 2.5 μA
• Output voltage: 1.1 to 6.0 V, selectable in 0.1 V steps.
• Output voltage accuracy: ±2.0%
• Output current: 50 mA capable (3.0 V output product, VIN=5 V) *1
75 mA capable (5.0 V output product, VIN=7 V) *1
• Dropout voltage: Typ. 160 mV (VOUT = 5.0 V, IOUT = 10 mA)
• Low ESR capacitor Ceramic capa citor of 0.1 μF or more can be used as an output capacitor.
• Short circuit protection for: Series A
• Excellent Line Regulation: Stable operation at light load of 1 μA
• Lead-free, Sn 100%, halogen-fre e*2
*1. Attention should be paid to the power dissipation of the package when the load is large.
*2. Refer to “ Product Name Structure” for details.
Applications
• Power source for battery -powered devices
• Power source for personal comm unication devices
• Power source for home electric/electronic appliance s
Packages
• SNT-4A
• SC-82AB
• SOT-23-5
• SOT-89-3
