The tle4253gs is a monolithic integrated low dropout tracking regulator in a small pg-dso-8 package.

Heat dissipation pad (EP) Package model PG-DSO-8 The heat dissipation pad provides very low thermal resistance . The IC Designed to provide off board systems in harsh conditions of automotive applications , For example, sensors in engine management system . therefore , The IC Equipped with additional reverse polarity protection and short circuit protection to ground and battery . When the power supply voltage gets 40 V when , The output voltage follows the reference voltage applied to the adjustment input , It has high precision . The minimum reference voltage directly applied to the regulating input or external resistance voltage divider can be 2.0 V. The output can drive up to 250 mA The load of .TLE4253 The tracker can be set to shutdown mode , To reduce the quiescent current to a very low value . This makes IC Suitable for low-power battery applications .
