DESCRIPTION  
ORDERING INFORMATION  
The EZ158X family of high performance positive  
voltage regulators are designed for use in applications  
requiring very low dropout voltage at 7, 5, 3 and 1.5  
amps. When supplying 2.5V on motherboards where  
both 5V and 3.3V supplies are available, the superior  
dropout characteristics of the EZ158X result in reduced  
heat dissipation compared to regular LDOs, thus  
allowing heat sink size reduction. Additionally, the  
EZ158X provides excellent regulation over variations in  
line, load and temperature. Remote sense operation  
allows compensating for trace, connector and other  
resistive losses.

Outstanding features include very low dropout  
performance at rated current, fast transient response,  
remote sense, internal current limiting, thermal  
shutdown and safe operating area protection of the  
output device. The EZ158X is a five terminal  
adjustable voltage regulator available in the popular 5  
pin TO-220 and TO-263 plastic packages.

PIN CONFIGURATION  
PIN DESCRIPTION  
Pin Pin Name  
Pin Function  
1
SENSE This pin is the positive side of the reference voltage for this device. With this pin it is possible to  
Kelvin sense the output voltage at the load.  
2
ADJUST / This pin is the negative side of the reference voltage for the device. Transient response can be  
improved by adding a small bypass capacitor from the adjust pin to ground.  
GROUND This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts,  
and should be connected to ground.  
3
4
OUTPUT This is the power output of the device, and is electrically connected to the TAB.  
CONTROL This pin is the supply pin for the control circuitry for the device. The current flow into this pin will  
be approximately 1% of the output current. For the device to regulate, the voltage at this pin must  
be between 1.0V and 1.3V greater than the output voltage (see dropout specifications).  
5
POWER This is the collector input to the power device of the EZ158X. The output load current is supplied  
through this pin. For the device to regulate, the voltage on this pin must be between 0.1V and  
0.7V greater than the output voltage, depending upon load current (see dropout specifications).

NOTES:  
(1) Capacitor values are for reference only. Good quality, low ESR tantalum or aluminum electrolytic capacitors  
should be used. Increasing the value of the output capacitor will improve the overall transient response.  
(2) If the same voltage is input to both POWER and CONTROL, then the dropout voltage will become 1.3V maxi-  
mum.  
(3) A small (~0.033µF) capacitor can be used to bypass the ADJUST pin to improve transient response, if needed.

APPLICATION INFORMATION  
DEVICE OUTLINE - TO-220, 5 PIN  
The EZ158X is a low dropout regulator designed to  
power the next generation of low voltage, split voltage  
plane processors, such as the Pentium® Processor  
P55C, the IBM PowerPC™ 603EV and 604EV and the  
AMD5K86™ and K6 Processors.  
The dropout voltage is minimized by utilizing a  
separate input voltage, VCONTROL, which should exceed  
VOUT by at least 1.3V. The 2.5V power for the load  
(microprocessor core) can be derived from a 3.3V  
system supply. Since the efficiency of a linear regulator  
is the ratio of the output to the input voltage, heat  
dissipation is reduced by using a 3.3 input, thereby  
lowering heatsink and cooling fan costs. For a load of  
7A at 2.5V, the regulator would dissipate 17.5W when  
converting from 5V, but only 5.6W from a 3.3V input.  
Remote Kelvin sensing of the output voltage can be  
achieved by connecting the sense pin to the output at  
the load. Remote sensing will reduce errors  
associated with resistive trace losses between  
regulator and processor.
