R1524x-Y Series
200 mA 36 V Input Ultra Low Supply Current VR for High Temperature Applications
NO.EA-354-150930
OUTLINE
The R1524x is a CMOS-based ultra low supply current voltage regulator featuring 200 mA output current and
36 V input voltage. This device consists of an Output Short-circuit Protection Circuit, an Over-current Protection
Circuit, and a Thermal Shutdown Circuit in addition to the basic regulator circuits. The operating temperature
range is between −40°C to 105°C, and the maximum input voltage is 36 V. All these features allow this device to
become an ideal power source for equipments used under high-temperature conditions.
The output voltages are internally fixed at either of the following: 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, 3.4 V, 5.0 V,
6.0 V, 8.0 V, 8.5 V and 9.0 V. The output voltage accuracy is ±0.6%.
The packages for this device range from high-density mounting to ultra high wattage. The R1524x is offered
in a 5-pin SOT-23-5, a 5-pin SOT-89-5, and a 6-pin HSOP-6J package.
