1.5 A, Adjustable Output, Negative Voltage Regulator The LM337 is an adjustable 3−terminal negative voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of −1.2 V to − 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow−out proof. The LM337 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM337 can be used as a precision current regulator. Features •Output Current in Excess of 1.5 A •Output Adjustable between −1.2 V and −37 V •Internal Thermal Overload Protection •Internal Short Circuit Current Limiting Constant with Temperature •Output Transistor Safe−Area Compensation

The MIC2954 is a “bulletproof” efficient voltage regulator with very low dropout voltage (typically 40mV @ light loads and 375mV @ 250mA), and low quiescent current (120µA typical). The quiescent current of the MIC2954 increases only slightly in dropout, thus prolonging battery life. Key MIC2954 features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient). Features • High-accuracy 5V, guaranteed 250mA output • Low quiescent current • Low dropout voltage • Extremely tight load and line regulation • Very low temperature coefficient • Current and thermal limiting • Input can withstand –20V reverse battery and+60V positive transients • Error flag warns of low output voltage • Logic-controlled electronic shutdown • Output programmable from 1.24V to 29V (MIC2954-07/08) • Available in TO-220, TO-92, and surface-mount SOT- 223 and SOIC-8 packages

The NCP565D2T12G is a 1.2V, 1.5A linear voltage regulator from ON Semiconductor. It is a low-dropout (LDO) regulator with a wide input voltage range of 2.7V to 18V. It features a low quiescent current of only 10μA and a fast transient response. The device is available in a D2PAK package and is ideal for applications requiring low power consumption and high accuracy.

The LE50CD linear voltage regulator from STMicroelectronics is a positive fixed voltage regulator with a single regulator, an output voltage of 5V, and a typical voltage dropout of 0.2V@100mA. It is designed for surface-mount applications and comes in an 8-SOIC package with a width of 0.154" (3.90mm). The current output is rated for a minimum of 150mA, and it is capable of operating in temperatures from -40°C to 125°C.
