The AS273 is a series of programmable over-temperature detectors. Each is internally composed of a precision 2.5 V shunt reference, a proportional-to-absolute temperature thermal sensor, a comparator with controlled hysteresis, and an open collector output that indicates an over-temp condition. The threshold for the over-temp signal can be set to any of three values on a given part by controlling the magnitude of the reference shunt current.
1. Programmable to three different over-temperature thresholds 2. 2.5 V temperature compensated bandgap reference trimmed to 1% 3. Open collector output goes low on over-temp condition

The TK111xxM is a low dropout linear regulator with a built in electronic switch. The internal 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 logic high level. An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 µVrms.
1. High Voltage Precision at ±2.0% or ±60 mV 2. Active High On/Off Control 3. Very Low Dropout Voltage (85 mV at 30 mA) 4. Very Low Noise 5. Miniature Package (SOT-23L-6) 6. Internal Thermal Shutdown 7. Short Circuit Protection 8. Excellent Ripple Rejection (70 dB @ 1 kHz) 9. Reverse Bias Protection
