Power dissipation(3) Internally

Limited

Junction temperature(3) –40 150 °C

Storage temperature, Tstg −65 150 °C

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Recommended Operating Conditions are

conditions under which operation of the device is ensured. Recommended operating ratings do not imply ensured performance limits.

For ensured performance limits and associated test conditions, see the Electrical Characteristics: LM3480-3.3, LM3480-5.

(2) If Military- or Aerospace-specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.

(3) The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (TJ– TA) / RθJA where

TJis the junction temperature, TAis the ambient temperature, and RθJA is the junction-to-ambient thermal resistance. The 370-mW

rating results from substituting the Absolute Maximum junction temperature, 150°C for TJ, 50°C for TA, and 269.6°C/W for RθJA. More

power can be safely dissipated at lower ambient temperatures. Less power can be safely dissipated at higher ambient temperatures.

The Absolute Maximum power dissipation can be increased by 3.7 mW for each °C below 50°C ambient. It must be derated by 3.7 mW

for each °C above 50°C ambient. Heat sinking enables the safe dissipation of more power. The LM3480 actively limits its junction

temperature to about 150°C.

7 Detailed Description

7.1 Overview

The LM3480 is an integrated linear voltage regulator with inputs that can be as high as 30 V. It ensures a

maximum dropout of 1.2 V at the full load of 100 mA. The LM3480 has different output options including 3.3-V, 5-

V, 12-V, and 15-V outputs, making LM3480 the tiny alternative to industry standard LM78Lxx series and similar

devices.

7.2 Functional Block Diagram

7.3 Feature Description

7.3.1 3.3-V, 5-V, 12-V, and 15-V Versions Available

The 3.3-V, 5-V, 12-V, and 15-V versions of LM3480 series are intended as tiny alternatives to industry standard

LM78Lxx series and similar devices.

7.3.2 1.2-V Ensured Maximum Dropout

The 1.2-V quasi-low dropout of the LM3480 series devices make them a nice fit in many application where the 2-

V to 2.5-V dropout of LM78Lxx series devices precludes their use.

7.4 Device Functional Modes

7.4.1 Operation with VIN =5V

The 3.3-V member of LM3480 can operate with an input of 5 V ±5%, its tiny SOT-23 package and quasi-low

dropout makes it suitable for providing a very tiny, 3.3-V, 100-mA bias supply from 5-V power supply.

8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LM3480 is a linear voltage regulator with 1.2-V ensured maximum dropout and 100-mA ensured minimum

load current. This device has 3.3-V, 5-V, 12-V, and 15-V versions. The implementation of LM3480 is discussed in

this section.

8.2 Typical Application

8.2.1 Design Requirements

DESIGN PARAMETER EXAMPLE VALUE

Input voltage 6.5 V

Output voltage 5 V

Output current 100 mA

8.2.2 Detailed Design Procedure

8.2.2.1 External Capacitors

A minimum input and output capacitance value of 0.1 µF is required for stability and adequate transient

performance. There is no specific ESR limitation, although excessively high ESR will compromise transient

performance. There is no specific limitation on a maximum capacitance value on the input or the output.

8.2.2.1.1 Output Capacitor

The minimum output capacitance required to maintain stability is 0.1 µF. Larger values of output capacitance can

be used to improve transient behavior.

8.2.3 Application Curves

Unless indicated otherwise, VIN = 6.5 V, VOUT =5V,COUT = 0.1 µF, and TA= 25°C

9 Power Supply Recommendations

The LM3480 is designed to operated from up to a 30-V input voltage supply. This input supply must be well

regulated. If the input supply is noisy, additional input capacitors with low ESR can help to improve the output

noise performance.

10 Layout

10.1 Layout Guidelines

For best overall performance, place all the circuit components on the same side of the circuit board and as near

as practical to the respective LDO pin connections. Place ground return connections to the input and output

capacitors, and to the LDO ground pin as close to each other as possible, connected by a wide, component-side,

copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and

negatively affects system performance. This grounding and layout scheme minimizes the inductive parasitic, and

thereby reduces load-current transients, minimizes noise, and increases circuit stability.

A ground reference plane is also recommended and is either embedded in the PCB itself or located on the

bottom side of the PCB opposite the components. This reference plane serves to assure accuracy of the output

voltage, shield noise, and behaves similar to a thermal plane to spread heat from the LDO device. In most

applications, this ground plane is necessary to meet thermal requirements.
