RH5VT21CC datasheet

 

Description

RH5VT21CC Series are voltage detector ICs with high threshold accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low voltage and is used, for instance, for system reset. Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy.

Features

1. Ultra-low Supply Current : TYP. 0.8μA (VDD=1.5V)
2. Broad Operating Voltage Range : 0.7V to 10.0V (Topt =25°C)
3. Detector Threshold :
Stepwise setting with a step of 0.1V in the range of 0.9V to 6.0V is possible (refer to Selection Guide).

4. High Accuracy Detector Threshold : ±2.5%
5. Low Temperature-Drift Coefficien of Detector Threshold : TYP. ±100ppm/°C
6. Two Output Types : Nch Open Drain and CMOS

Applications

1. CPU & Logic Circuit Reset
2. Battery Checker
3. Window Comparator
4. Wave Shaping Circuit
5. Battery Back-Up Circuit
6. Power Failure Detector

TK73280MIL Datasheet PDF – 8.0V, Low Dropout Regulator – Toko

Posted on by pinout

Part Number: TK73280MIL

Function: 8.0V, Low Dropout Regulator

Package: SOT-23L-8 Type

Manufacturer: Toko America Inc

Pinouts:

TK73280MIL datasheet

 

Description

The TK73280MIL is a controller IC for a low dropout voltage regulator. The TK732xx and the external PNP power transistor provide standard output voltages from 2 to 11 V and output current from 100 mA to 5 A. By utilizing an external PNP power transistor, low dropout voltage at high current can be readily achieved. The internal electronic switch can be controlled by TTL or CMOS logic levels. The device is in the “on” state when the control pin is pulled to a high logic level. A pin for a bypass capacitor, which connects to the internal circuitry, is provided to lower the overall output noise level.

 

Features

1. Up to 5 A Output Current Capability With External PNP Transistor
2. Internal Short Circuit Protection
3. Excellent Load Regulation
4. CMOS/TTL-Compatible On/Off Switch
5. Internal Reverse Bias Current Protection Switch
6. Internal Thermal Shutdown
7. Broad Operating Voltage Range
8. High Impedance VSENSE Pin (Off Mode)
9. Continuous and Pulsed Current Modes

Applications

1. Battery Powered Systems
2. Cellular/Cordless Telephones
3. Radio Control Systems
4. Wireless Communications Systems
5. Portable Instrumentations
6. Portable Computers
7. Personal Digital Assistants
8. Local Area Network (LAN) Receivers
9. Lithium Ion Battery Chargers
10. Power Recovery for Microprocessors
