The LMS1585ACSX-1.5 is a low drop-out regulator (LDO) linear voltage regulator which is capable of providing up to 1.5A output current with a drop-out voltage of 250mV at 1.5A. It is well suited to a wide range of applications from low voltage, low power applications such as handheld electronics to higher power, higher voltage applications such as automotive electronics.

The primary application field of LMS1585ACSX-1.5 are wide ranging and suitable for many low drop-out linear applications. This LDO can be found in use in portable electronics, handheld devices, automotive electronics, industrial and medical devices, lighting, etc. It is a very efficient and cost effective regulator and can be used in many different types of applications.

This particular regulator has a Thermal Protection feature which is designed to protect the device from entering thermal overload conditions due to over power dissipation or prolonged high temperature operation. This added feature is useful for applications which require a fail-safe safety setting. The LDO also has a Shutdown Mode, which can be used to completely disable the output of the device. This can prove invaluable for applications which need complete control of the output current at all times.

The working principle of the LMS1585ACSX-1.5 is very simple and is based on the comparison of a reference voltage and the output voltage. The reference voltage is generated by a bandgap reference circuit, and it is compared with the output voltage through an error amplifier. The output voltage is adjusted by changing the gain of the error amplifier, thus bringing the error voltage to zero. The output voltage is then linearly regulated regarding to the reference voltage.

The LMS1585ACSX-1.5 is a very versatile LDO linear voltage regulator which is capable of providing up to 1.5A current at a drop-out voltage of 250mV. Its primary applications includes portable electronics, automotive, industrial and medical, lighting and many other low voltage, low power applications. Its operating principle is based on the comparison of the reference voltage and the output voltage. Its Thermal Protection feature and Shutdown mode are particularly useful for applications which require a fail-safe and complete control.
