S-19700
Automotive, 125°C Operation, 36 V Input, 400 mA Voltage Regulator with Current Monitor And Adjustable Current Limit S-19700 Series Describe: The S-19700 Series, developed by using CMOS technology, is a positive voltage regulator with a current monitoring function for 125°C automotive operation. It provides an output current of 400 mA min., and a ceramic capacitor of 4.7 μF or more can be used as the output capacitor. Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be controlled as the small value 15 μA typ. The current monitor monitors the current flowing to the voltage regulator and outputs the voltage according to the external resistance, and limits the current value from exceeding the set value. The S-19700 Series has two types of products of which one is the externally set product whose output voltage is determined by the external divided-resistor, and the other is the internally set product which includes an INT pin and whose output voltage is fixed. Features:
During operation: 80 μA typ., 170 μA max. (Tj = −40°C to +150°C) During power-off: 1.0 μA typ., 5.0 μA max. (Tj = −40°C to +90°C)
*1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large. *2. Contact our sales representatives for details. Applications:

S-19680
Automotive, 105°C Operation, High Side Switch with Current Monitor S-19680 Series Describe: The S-19680 Series, developed by using CMOS technology, is a high side switch with the current monitor function. When the Pch output transistor is turned on, voltage is supplied to the load connected to the OUT pin. Monitoring the current which flows from the VIN pin to the OUT pin by using two external resistors, the S-19680 Series limits the current so that it does not exceed the set value. Depending on the monitored current value, the S-19680 Series detects the short-circuit status or the open status of the load connected to the OUT pin, and outputs an alarm signal. In addition, the S-19680 Series has the ON / OFF circuit to control the Pch output transistor’s status, ON and OFF, and the thermal shutdown circuit to limit overheating. The hysteresis type or latch type can be selected for the thermal shutdown circuit. Features: • Power supply voltage: VDD = 2.7 V to 10.0 V • Current consumption during operation: ISS1 = 12 μA typ., ISS1 = 24 μA max.
