750mA CMOS
Elektronische Bauelemente
Positive Voltage Regulator
RoHS Compliant Product
Description
The S5J2167 series positive,linear regulators feature low quiescent
current (45µA typ.) with low dropout voltage, making them ideal
for battery applications. Output voltage are set at the factory and
trimmed to 1.5% accuracy.These rugged devices have both
Thermal Shutdown and Current Fold-back to prevent device failure
under the "Worst" of operating conditions. An additional feature is a
"Power Good" detector, which pulls low when the output is out of
with an output capacitance of
regulation.The S5J2167 is stable
4.7µF or greater.

Detailed Description
The S5J 2167 of COMS regulators contain a PMOS pass transistor,voltage reference, error amplifier,over-current protection and thermal
shutdown.The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal protection circuits.
During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal shutdown circuits
become active when the junction temperature exceeds140oC, or the current exceeds 2.2A.During thermal shutdown, the output voltage
remains low. Normal operation is restored when the junction temperature drops below 120oC.The S5J 2167 behaves like a current
Ω
source when the load reaches 2.2A. However, if the load impedance drops below 0.3
, the current drops back to 600mA to prevent
excessive power dissipation. Normal operation is restored when the load resistance exceeds of 0.75Ω .
External Capacitors
The S5J 2167 is stable with an output capacitance to ground of 4.7uF or greater. Ceramic capacitors have the lowest ESR, and will
offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC
response. Unfortunately, large value ceramic capacitors are comparatively expensive. One option is to parallel a 0.1uF ceramic
capacitor with a 10uF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low overall cost. A second capacitor is
recommended between the input and ground to stabilize VIN. The input capacitor should be at least 0.1uF to have a beneficial
effect. All capacitors should be placed in closed proximity to the pins. A "Quiet" ground termination is desirable. This can be
achieved with a "Star" connection.
Enable
When EN pin is pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the quiescent
Ω
current is less than 2uA. This pin behaves much like an electronic switch. 100K resistor is necessary between VEN source and EN
pin when VEN is high than VIN. (Note: There is no internal pull-up for EN pin. It can not be floating.)
Power Good
The S5J 2167 includes the Power Good feature. When the output in not within
15% of the specified voltage, it pulls low. This can
occur under the following conditions:
1. Input voltage too low.
2. During over-temperature.
3. During over-current.
4. If output is pulled up.
( Note: PG pin is an open-drain output.)
