Seiko Instruments has introduced the S-818 Series of extremely low quiescent current LDO voltage regulators. Packaged in the miniature SOT-23-5 or SOT-89-5 casings, the S-818 is a positive LDO voltage regulator developed using CMOS technology. The low power consumption and high-output current allow the S-818 to be used in a wide range of applications, such as cellular phones, PDAs, MP3 players, notebook PCs, handheld games, home security, digital cameras and portable audio devices.
The S-818 features a low quiescent current of typically 100nA (500nA max) with the power off and typically 30A (40A max) during operation.
Additional features include a low drop out voltage of 170mV typical, a high output current of 200mA for the 3V version and 300mA for the 5V version; and a high precision output voltage ranging from 2 to 6V.
The S-818 has a built-in power-off circuit, which ensures long battery life, and a built-in low on-resistance transistor provides low dropout voltage and large output current.
Pricing begins at $0.45 in quantities of 3000 for the SOT-23-5 packaging and $0.45 each in quantities of 1000 for the SOT-89-5 packaging.
