DESCRIPTION

The SPX2969 is a low dropout linear regulator with integrated PNP pass transistor. This part is

designed for high voltage applications, which can withstand up to 45V and 125°C. The output

voltage is set at a fixed 5V, and the part is guaranteed to deliver at least 150mA. The SPX2969

provides multiple protection mechanisms, including over-temperature and over-current detec-

tion. The part has a built-in reset circuit to monitor when the output voltage is below 4.65V. The

reset voltage threshold can be programmed down to 3.5V using an external resistor voltage

divider, while the reset timing can be programmed via an external capacitor. A built in comparator

compares the signal at the pin SI, normally fed by a voltage divider from the input voltage, with

the reference and gives an early warning on the pin SO. Both the sense output and the reset

output delay signals contain integrated 20kΩ pull up resistors. The part is available in an 8 Pin

NSOIC package.

SPX2969 150mA Low Dropout Voltage Regulator

APPLICATIONS INFORMATION

The input capacitor C

is necessary for compensating line influences. Using a resistor of

approximately 1Ω in series with C

, the oscillating circuit consisting of input inductance and input

capacitance can be damped. The output capacitor C

is necessary for the stability of the

regulating circuit. Stability is guaranteed at values

≥

10µF and at an ESR

≤

10Ω within the

operating temperature range. The delay pin capacitor's variation and temperature coefficient

may cause a small difference in the reset delay.
