HIGH RIPPLE-REJECTION LDO
REGULATOR
DESCRIPTION
The UTC LR1121B is CMOS-based voltage regulator ICs with
high output voltage accuracy, extremely low current, low
ON-resistance, and high Ripple Rejection.
An ON/OFF circuit enables the output to be turned off, ensuring
a long battery life. a built-in low on-resistance transistor provides a
low dropout voltage and large output current, and a built-in
overcurrent protector prevents the load current from exceeding the
current capacitance of the output transistor.
The line transient response and load transient of the UTC
LR1121B is excellent.
FEATURES
* Ultra-low supply current :
During operation: 30μA typ.
During standby: 0.1μA typ.

集成电路 IC UTC LS3718
信息内容：品牌/商标 UTC（台湾友顺） 型号/规格 LS3718 批号 09 封装 SOP-28 类型 其他IC 20-BIT SERIAL TO PARALLELCONVERTER DESCRIPTIONThe UTC LS3718 is a 20-bit serial to parallel converter utilizingCMOS Technology. It is incorporates control circuit, shift register,latch and driver into a single ship. It is suitable for MCU interface.The effective interface assignment of MPU is available as theconnection between UTC LS3718 and MPU is required only 4lines.The device is designed to operate up to 5MHz. When the serialdata input to the DATA terminal and the data is output from paralleloutput buffer through serial in parallel out shift register and paralleldata latches.The data can through the shift register serial output to the SOterminal. Therefore the UTC LS3718 can cascade connection toexpand the output data num...
热销正电压稳压器UTC（台湾友顺） UR6225
信息内容：品牌/商标 UTC(台湾友顺） 型号/规格 UR6225 封装 TO-92,SOT-23,25,89 批号 10 类型 稳压IC POSITIVE VOLTAGE REGULATOR DESCRIPTIONThe UTC UR6225 is a positive voltage output, three-pinregulator that provides a high current even when the input/outputvoltage differential is small. Low power consumption and highaccuracy is achieved through CMOS and laser trimmingtechnologies.The UTC UR6225 consists of a high-precision voltagereference, an error amplification circuit, and a current limited outputdriver. Transient responses to load variations have improved incomparison to the existing series. FEATURES* Maximum Output Current: 300mA(Within Max.
