CS8128 General Description

The CS8128 contains all the necessary control circuitry to implement a 5V linear regulator. An external pass device is used to produce superior performance compared to conventional monolithic regulators. The CS8128 with a TIP42 PNP transistor typically provides a 100mV dropout voltage at 500mA, increasing to 350mV at 3A. Quiescent current at 500mA is only 5mA. Monolithic regulators cannot approach these figures because their power transistors do not provide the high beta and excellent saturation characteristics at high currents. The CS8128 is compatible with a wide variety of external transistors, allowing flexibility for thermal, space, and cost management.

The CS8128 includes thermal shutdown and externally programmable current limit and over-voltage shutdown, making it suitable for use in automotive and
switching regulator post regulator applications. An optional external RC filter added to the CS8128 supply lead provides EMC hardening in addition to the on-chip EMC hardening. The SENSE lead allows remote sensing of the output voltage for improved regulation.

An active microprocessorRESET function is included on-chip with externally programmable delay time. During power-up, or after detection of any error in the regulated output, the RESET lead will remain in the low state for the duration of the delay. Types of errors include short circuit, low input voltage, overvoltage shutdown, thermal shutdown, or others that cause the output to become unregulated. This function is independent of the input voltage and will function correctly with an output voltage as low as 1V. Hysteresis is included in both the reset and delay comparators for noise immunity and to prevent oscillations. A latching discharge circuit is used to discharge the delay capacitor, even when triggered by a relatively short fault condition. This circuit improves upon the commonly used SCR structure by providing improved noise immunity and full capacitor discharge (0.2V typ).

CS8129 General Description

The CS8129 is a precision 5V linear reg- ulator capable of sourcing 750mA. The RESET threshold voltage has been lowered to 4.2V so that the regulator can be used with 4V microprocessors.

The lower RESET threshold also per- mits operation under low battery condi- tions (5.5V plus a diode). The RESET's delay time is externally programmed using a discrete RC network. During power up, or when the output goes out of regulation, RESET remains in the low state for the duration of the delay.

This function is independent of the input voltage and will function correct- ly as long as the output voltage remains at or above 1V. Hysteresis is included in the Delay and the RESET comparators to improve noise immunity. A latching discharge circuit is used to discharge the delay capacitor when it is triggered by a brief fault condition.

The regulator is protected against a variety of fault conditions: i.e. reverse battery, overvoltage, short circuit and thermal runaway conditions. The regu- lator is protected against voltage tran- sients ranging from -50V to +40V. Short circuit current is limited to 1.2A (typ).
The CS8129 is packaged in a 5 lead TO-220 and a 16 lead surface mount package.
