MIC5219

500mA-Peak Output LDO Regulator

General Description

The MIC5219 is an efficient linear voltage regulator with high

peak output current capability, very-low-dropout voltage, and

better than 1% output voltage accuracy. Dropout is typically

10mV at light loads and less than 500mV at full load.

The MIC5219 is designed to provide a peak output current for

start-up conditions where higher inrush current is demanded.

It features a 500mA peak output rating. Continuous output

current is limited only by package and layout.

The MIC5219 can be enabled or shut down by a CMOS or

TTL compatible signal. When disabled, power consumption

drops nearly to zero. Dropout ground current is minimized to

help prolong battery life. Other key features include reversed-

battery protection, current limiting, overtemperature shutdown,

and low noise performance with an ultra-low-noise option.

The MIC5219 is available in adjustable or fixed output volt-

ages in the space-saving 6-pin (2mm

, 6-pin

SOT-23-5 and MM8

Notes:

MIC5219

1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating

the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, T

(max),

the junction-to-ambient thermal resistance,

, and the ambient temperature, T

. The maximum allowable power dissipation at any ambient

temperature is calculated using: P

(max) = (T

(max) – T

)

÷ θ

. Exceeding the maximum allowable power dissipation will result in excessive die

temperature, and the regulator will go into thermal shutdown. See Table 1 and the “Thermal Considerations” section for details.

2. The device is not guaranteed to function outside its operating rating.

3. Specification for packaged product only.

4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.

5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range

from 100µA to 500mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.

6. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differen-

tial.

7. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load

current plus the ground pin current.

8. V

is the voltage externally applied to devices with the EN (enable) input pin.

9. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regu-

lation effects. Specifications are for a 500mA load pulse at V

= 12V for t = 10ms.

10. C

BYP

is an optional, external bypass capacitor connected to devices with a BYP (bypass) or ADJ (adjust) pin.
