LT1121CN8 by Linear Technology -- Micropower Low Dropout Regulators with Shutdown.

LP3965 -- 1.5A Fast Ultra Low Dropout Linear Regulators.

The LP3965 series of fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. These ultra low dropout linear regulators respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications. The LP3965 is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3965 to operate under extremely low dropout conditions.

The MIC29500-3.3BT is a fixed positive, high current, high accuracy, low-dropout voltage regulator by Micrel Inc. Package/Case is TO-220-3.

SC1133CT is a combination switching controller and low dropout regulator. Package/Case is TO-220. This part appears to be the adjustable version of this part.

LP2950ACN 100mA Low Dropout Voltage Regulator by Alpha (later acquired by Sipex)

[Note: Alpha was originally a subsidiary of Calogic. Alpha was acquired by Sipex in 1999 when Sipex acquired Calogic. The below information is taken from the Sipex datasheet on this part.]

The LP2950 is a low power voltage regulator. The LP2950 features low quiescent current and very low dropout voltage (Typ. 50mV at light load and 380 mV at 100mA). This includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation 0.05% typ., and very low output temperature coefficient, making the LP2950 useful as a low-power voltage reference.

These parts are new and unused.

The EZ1585CT-2.5 is a 4.6Amp, fixed, low dropout, positive voltage regulator. The package/case is TO-220.

EZ1588CT-2.5 is a low dropout positive voltage regulator by Semtech.

The EZ1588 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1588 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1588 series are three terminal regulators.

The EZ1587 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at up to 3A. Additionally, the EZ1587 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device.
