LM2936Q

Ultra-Low Quiescent Current LDO Voltage Regulator

General Description

Features

The LM2936Q ultra-low quiescent current regulator features

low dropout voltage and low current in the standby mode. With

less than 15 μA quiescent current at a 100 μA load, the

LM2936Q is ideally suited for automotive and other battery

operated systems. The LM2936Q retains all of the features

that are common to low dropout regulators including a low

dropout PNP pass device, short circuit protection, reverse

battery protection, and thermal shutdown. The LM2936Q has

a 40V maximum operating voltage limit, a −40°C to +125°C

operating temperature range, and ±3% output voltage toler-

ance over the entire output current, input voltage, and tem-

perature range. The LM2936Q is available in a SO-8

package, SOT-223 surface mount package and TO-252 sur-

face mount package.

Typical Application

30131901

* Required if regulator is located more than 2″ from power supply filter capacitor.

** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating temperature range. Effective series resis-

tance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without

bound.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating

the device beyond its specified operating ratings.

Note 2: Human body model, 100 pF discharge through a 1.5 kΩ resistor.

Note 3: The maximum power dissipation is a function of T_Jmax, θ_JA, and T_A. The maximum allowable power dissipation at any ambient temperature is

P_D= (T_Jmax− T_A)/θ_JA. If this dissipation is exceeded, the die temperature will rise above 150°C and the LM2936Q will go into thermal shutdown.

Note 4: Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm.

Note 5: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.

Note 6: To ensure constant junction temperature, pulse testing is used.

copper pad area directly under the ground tab will improve the

_JArating to approximately 50°C/W.

Applications Information

Unlike other PNP low dropout regulators, the LM2936Q re-

mains fully operational to 40V. Owing to power dissipation

characteristics of the available packages, full output current

cannot be guaranteed for all combinations of ambient tem-

perature and input voltage.

While the LM2936Q has an internally set thermal shutdown

point of typically 160°C, this is intended as a safety feature

only. Continuous operation near the thermal shutdown tem-

perature should be avoided as it may have a negative affect

on the life of the device.

The junction to ambient thermal resistance θ_JArating has two

distinct components: the junction to case thermal resistance

rating θ_JC; and the case to ambient thermal resistance rating

While the LM2936Q maintains regulation to 60V, it will not

withstand a short circuit above 40V because of safe operating

area limitations in the internal PNP pass device. Above 60V

the LM2936EP will break down with catastrophic effects on

the regulator and possibly the load as well. Do not use this

device in a design where the input operating voltage may ex-

ceed 40V, or where transients are likely to exceed 60V.

_CA. The relationship is defined as: θ_JA= θ_JC+ θ_CA.

For the SO-8 and TO-252 surface mount packages the θ_JA

rating can be improved by using the copper mounting pads

on the printed circuit board as a thermal conductive path to

extract heat from the package.

Shutdown Pin

On the SO-8 package the four ground pins are thermally con-

nected to the backside of the die. Adding approximately 0.04

square inches of 2 oz. copper pad area to these four pins will

improve the θ_JArating to approximately 110°C/W. If this extra

pad are is placed directly beneath the package there should

not be any impact on board density.

The LM2936QHBMA–5.0 has a pin for shutting down the reg-

ulator output. Applying a Logic Level High (>2.0V) to the

Shutdown pin will cause the output to turn off. Leaving the

Shutdown pin open, connecting it to Ground, or applying a

Logic Level Low (<0.6V) will allow the regulator output to turn

on.

On the TO-252 package the ground tab is thermally connect-

ed to the backside of the die. Adding 1 square inch of 2 oz.
