NCP553, NCV553 Voltage Regulator - CMOS, Low Iq, NOCAPE 80 mA This series of fixed output NOCAP linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent. This series features an ultra−low quiescent current of 2.8 mA. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits. These voltage regulators have been designed to be used with low cost ceramic capacitors. The devices have the ability to operate without an output capacitor. The devices are housed in the micro−miniature SC82−AB surface mount package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V. Other voltages are available in 100 mV steps.

The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected. Dropout Voltage The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 3.0% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Line Transient Response Typical over and undershoot response when input voltage is excited with a given slope. Thermal Protection Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated at typically 160°C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. Maximum Power Dissipation The maximum total dissipation for which the regulator will operate within its specifications. Quiescent Current The quiescent current is the current which flows through the ground when the LDO operates without a load on its output: internal IC operation, bias, etc. When the LDO becomes loaded, this term is called the Ground current. It is actually the difference between the input current (measured through the LDO input pin) and the output current. Maximum Package Power Dissipation The maximum power package dissipation is the power dissipation level at which the junction temperature reaches its maximum operating value, i.e. 125°C. Depending on the ambient power dissipation and thus the maximum available output current. www.onsemi.com 4 NCP553, NCV553 1 3.03 Vout(nom.) = 3.0 V 0.9 Vout, OUTPUT VOLTAGE (VOLTS) Vin − Vout, DROPOUT VOLTAGE (VOLTS) TYPICAL CHARACTERISTICS 0.8 0.7 80 mA 0.6 0.5 0.4 40 mA 0.3 0.2 0.1 0 −50 −25 0 50 25 75 100 Vout(nom.) = 3.3 V 3.025 Iout = 5 mA 3.02 3.01 3.005 3 −60 125 −20 −40 40 20 0 80 60 TEMPERATURE (_C) TEMPERATURE (_C) Figure 2.

As power across the NCP553 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material and also the ambient temperature effect the rate of temperature rise for the part. This is stating that when the devices have good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. The maximum dissipation the package can handle is given by: Input Decoupling (C1) A 1.0 mF capacitor either ceramic or tantalum is recommended and should be connected close to the package. Higher values and lower ESR will improve the overall line transient response. If large line or load transients are not expected, then it is possible to operate the regulator without the use of a capacitor. TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K Output Decoupling (C2) T *TA PD + J(max) RqJA The NCP553 are very stable regulators and do not require any specific Equivalent Series Resistance (ESR) or a minimum output current. If load transients are not to be expected, then it is possible for the regulator to operate with no output capacitor. Otherwise, capacitors exhibiting ESRs ranging from a few mW up to 10 W can thus safely be used. The minimum decoupling value is 0.1 mF and can be augmented to fulfill stringent load transient requirements. The regulator accepts ceramic chip capacitors as well as tantalum devices. Larger values improve noise rejection and load regulation transient response. TDK capacitor: C2012X5R1C105K, C1608X5R1A105K, or C3216X7R1C105K If junction temperature is not allowed above the maximum 125°C, then the NCP553 can dissipate up to 250 mW @ 25°C. The power dissipated by the NCP553 can be calculated from the following equation: Ptot + ƪVin * Ignd (Iout)ƫ ) [Vin * Vout] * Iout or P ) Vout * Iout VinMAX + tot Ignd ) Iout If an 80 mA output current is needed then the ground current from the data sheet is 2.8 mA. For an NCP553 (3.0 V), the maximum input voltage will then be 6.12 V. Hints Please be sure the Vin and GND lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction. Set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible.
