DATASHEET ISL80136 FN7970 Rev.4.00 Aug 8, 2019 40V, Low Quiescent Current, High Accuracy, 50mA Linear Regulator The ISL80136 is a high voltage, low quiescent current linear regulator ideally suited for “always-on” and “keep alive” applications. The ISL80136 operates from an input voltage of +6V to +40V under normal operating conditions, consuming only 18µA of quiescent current at no load. Features The ISL80136 offers adjustable output voltages from 2.5V to 12V. It features an EN pin that can be used to put the device into a low-quiescent current shutdown mode where it draws only 1.8µA of supply current. The device features over-temperature shutdown and current limit protection. • Ultra low 18µA typical quiescent current The ISL80136 is rated across the -40°C to +125°C temperature range and is available in an 8 lead EPSOIC with an exposed pad package. • Low 26µVRMS noise Applications • Stable operation with 10µF output capacitor • Industrial • Thermal shutdown and current limit protection • Networking Related Literature • Wide VIN range of 6V to 40V • Adjustable output voltage from 2.5V to 12V • Ensured 50mA output current • Low 1.8µA of typical shutdown current • ±1% accurate voltage reference (over temperature, load) • Low dropout voltage of 120mV at 50mA • 40V tolerant logic level (TTL/CMOS) enable input • 5kV ESD HBM rated • Telecom For a full list of related documents, visit our website: • ISL80136 device page OUT IN CIN 0.1µF R1 EN PAD (GND) ADJ R2 GND COUT 10µF QUIESCENT CURRENT (µA) 70 60 40 30 20 FN7970 Rev.4.00 Aug 8, 2019 LOAD = 0mA 10 0 -50 FIGURE 1.

DWG. # Evaluation Platform NOTES: 1. See TB347 for details about reel specifications. 2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 3.
