Description

The LM140L series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications. The LM140LA is an improved version of the LM78LXX series with a tighter output voltage tolerance (specified over the full military temperature range), higher ripple rejection, better regulation and lower quiescent current.

The LM140LA regulators have ±2% VOUT specification, 0.04%/V line regulation, and 0.01%/mA load regulation. When used as a zener diode/resistor combination replacement, the LM140LA usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation.

The voltages available allow the LM140LA to be used in logic systems, instrumentation, Hi-Fi, and other solid state electronic equipment. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Description

The APL5522 is a dual low dropout regulator with output 1 with 3. 3V/ 0. 5A and output 2with 2. 5V/ 0. 5A output capability . In order to obtain lower drop-out voltage and faster transient response, which is critical for low voltage applications, the APL5522 has been optimized. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2 typical dropout voltage is 630mV at 500mA loading. Current limit is trimmed to ensure specifi ed output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.

Features

• Fixed Output Voltage :
(1) VOUT1=3.3V/500mA (within Maximum Power Dissipation)
(2) VOUT2=2.5V/500mA (within Maximum Power Dissipation)

• Low  Dropout Voltage (Defined as the Minimum Input/Output  Voltage  Difference) :
(1) Output 1  Dropout V oltage  : 550mV  (at 500mA)
(2) Output 2  Dropout V oltage  : 630mV  (at 500mA)

• Stable with 4.7mF Output Capacitor(at VOUT1)

• No Protection Diodes Needed

• Built-In Thermal Protection

• Built-In Current-Limit Protection

• Fast transient Response

• Short Setting Time

• Lead Free and Green Devices Available (RoHS Compliant)
