The S-L2980 series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and
low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and a large output current. A shutdown
circuit ensures long battery life.
Various types of output capacitors can be used in the S-L2980 series compared with the conventional CMOS
voltage regulators. A small ceramic capacitor can also be used.
Features
Output voltage:
1.5 V to 6.0 V, selectable in 0.1 V steps
High accuracy output voltage: ±2.0 % accuracy
Low dropout voltage:
120 mV typ. (at 3.0 V output product, IOUT=50 mA)
Low current consumption:
During operation: 90
μA typ., 140 μA max.
During shutdown: 0.1
μA typ., 1.0 μA max.
High peak current capability:
150 mA output is possible. (at VIN≥VOUT(S)+1.0 V)
*1
Built-in shutdown circuit:
Ensure long battery life.
Low ESR capacitor:
A 1.0
μF capacitor can be used as the output capacitor.
(A 2.2
μF capacitor can be used as the output capacitor for the products
whose output voltage is 1.7 V or less.)
High ripple rejection:
70 dB typ. (at 1.0 kHz)
Lead-free, Sn 100%, halogen-free*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 supply for battery-powered devices
Power supply for personal communication devices
Power supply for home electric/electronic appliances
Power supply for cellular phones
