The output of the regulator. A minimum of 4.7µF capacitor (0.05Ω ≤ ESR ≤ 0.5Ω) must be connected

from this pin to ground to insure stability. For improved ac load response a larger output capacitor is

recommended.

The input pin of regulator. Typically a large storage capacitor (0.05Ω ≤ ESR ≤ 0.5Ω) is connected from

this pin to ground to ensure that the input voltage does not sag below the minimum dropout voltage

during the load transient response. This pin must always be 1.3V higher than V_OUTin order for the

To ensure correct operation without entering dropout V_INmust be 1.5V greater than output voltage. Device will continue to operate below this minimum

input voltage under dropout conditions.

6. ZLDO1117Q contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature

exceeded. When activated, typically at +150°C, the regulator Output switches off and then back on as the die cools.

7. The maximum power dissipation is a function of T_J(max), θ_JAand T_A. The maximum allowable power dissipation at any ambient temperature is

P_D= (T_J(max)– T_A)/θ_JA

.

Notes: 11. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction

temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18‖ from the package.

12. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input

and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.

13. The minimum Load current is defined as the minimum output current required to maintain voltage regulation. This output current can be made up of either

load current itself and/or the current delivered to the output voltage setting feedback resistors.

ZLDO1117Q

Application Information

The ZLDO1117Q family of quasi-LDO regulators is easy to use. They are protected against short circuit and thermal overloads.

Thermal protection circuitry will shut down the regulator should the junction temperature exceed +150°C at the sense point. The ZLDO1117Q is

pin compatible with similar ‗1117 regulators and offers extended temperature range and improved regulation specifications.

Operation

The ZLDO1117Q develops a 1.25V reference voltage between the output and the adjust terminal. By placing a resistor between these two

terminals, a constant current is caused to flow through R1 and down through R2. For fixed output variants Resistors R1 and R2 are internal.

Stability

The ZLDO1117Q requires an output capacitor as part of the device frequency compensation. As part of its improved performance over industry

standard 1117 the ZLDO1117Q is suitable for use with MLCC (Multi Layer Ceramic Chip) capacitors. A minimum of 4.7µF ceramic X7R, 4.7µF

tantalum, or 47µF of aluminum electrolytic is required. The ESR of the output capacitor should be less than 0.5Ω. Surface mount tantalum

capacitors, which have very low ESR, are available from several manufacturers. When using MLCC capacitors avoid the use of Y5V dielectrics.

Load Regulation

For improved load regulation the ZLDO1117Q-ADJ should have the upper feedback resistor, R1, connected as close as possible to V_OUTand

the lower resistor, R2, connected as close as possible to the load GND return. This helps reduce any parasitic resistance in series with the load.

Thermal Considerations

ZLDO1117Q series regulators have internal thermal limiting circuitry designed to protect the device during overload conditions. For continuous

normal load conditions however, the maximum junction temperature rating of +125°C must not be exceeded.

It is important to give careful consideration to all sources of thermal resistance from junction to ambient. For the SOT223 and TO252 (DPAK)

packages, which are designed to be surface mounted, additional heat sources mounted near the device must also be considered. Heat sinking is

accomplished using the heat spreading capability of the PCB and its copper traces. The _JC(junction to tab) of the TO252 (DPAK) and SOT223

are +12°C/W and +16°C/W respectively.

Thermal resistances from tab to ambient can be as low as +30°C/W. The total thermal resistance from junction to ambient can be as low as

+42 to +46°C/W. This requires a reasonable sized PCB with at least one layer of copper to spread the heat across the board and couple it into

the surrounding air. Datasheet specifications using 2 oz copper and a 5mmx5mm pad with T_A= +27°C, no air flow yielded _JA(junction to tab) of

+73°C/W and +107°C/W for TO252 (DPAK) and SOT223 respectively.

The thermal resistance for each application will be affected by thermal interactions with other components on the board. Some experimentation

will be necessary to determine the actual value.

Ripple Rejection

When using the ZLDO1117Q adjustable device the adjust terminal can be bypassed to improve ripple rejection. When the adjust terminal is

bypassed the required value of the output capacitor increases.

The device will require an output capacitor of 22µF tantalum or 150µF aluminum electrolytic when the adjust pin is bypassed. Normally, capacitor

values on the order of 100µF are used in the output of many regulators to ensure good load transient response with large load current changes.

Output capacitance can be increased without limit and larger values of output capacitance further improve stability and transient response.

The curves for Ripple Rejection were generated using an adjustable device with the adjust pin bypassed. These curves will hold true for all

values of output voltage. For proper bypassing, and ripple rejection approaching the values shown, the impedance of the adjust pin capacitor, at

the ripple frequency, should be < R1. R1 is normally in the range of 100Ω to 200Ω. The size of the required adjust pin capacitor is a function of

the input ripple frequency. At 120Hz, with R1 = 100Ω, the adjust pin capacitor should be >13µF. At 10kHz only 0.16µF is needed.

For fixed voltage devices, and adjustable devices without an adjust pin capacitor, the output ripple will increase as the ratio of the output voltage

to the reference voltage (V_OUT/V_REF). For example, with the output voltage equal to 5V, the output ripple will be increased by the ratio of

5V/1.25V. It will increase by a factor of four. Ripple rejection will be degraded by 12dB from the value shown on the curve.
