DESCRIPTION

The ZXCL series have been designed with space sensitive systems in mind. They are available in the ultra small SC70-5 package, which is half the size of other SOT23 based regulators. The devices can be used with all types of output capacitors including low ESR ceramics and typical dropout voltage, is only 85mV at 50mA load. Supply current is minimised with a ground pin current of only 50/H9262A at full 150mA load. Logic control allows the devices to be shut down, consuming typically less than 10nA. These features make the device ideal for battery powered applications where power economy is critical.

In common with many other LDO regulators, the ZXCL device has an inherent diode associated with the output series pass transistor. This diode has its anode connected to the output and its cathode to the input. The internal diode is normally reverse biased, but will conduct if the output is forced above the input by more than a V BE (approximately 0.6V). Current will then flow from Vout to Vin. For safe operation, the maximum current in this diode should be limited to 5mA continuous and 30mA peak. An external schottky diode may be used to provide protection when this condition cannot be satisfied. Increased Output current Any ZXCL series device may be used in conjunction with an external PNP transistor to boost the output current capability. In the application circuit shown below, a FMMT717 device is employed as the external pass element. This SOT23 device can supply up to 2.5A maximum current subject to the thermal dissipation limits of the package (625mW). Alternative devices may be used to supply higher levels of current. Note that with this arrangement, the dropout voltage will be increased by the V BE drop of the external device. Also, care should be taken to protect the pass transistor in the event of excessive output current. ZXCL Series ISSUE 7 - AUGUST 2002 Scheme to boost output current to 2A

APPLICATIONS INFORMATION (Cont) Power Dissipation The maximum allowable power dissipation of the device for normal operation (Pmax), is a function of the package junction to ambient thermal resistance ( θja), maximum junction temperature (Tjmax), and ambient temperature (Tamb), according to the expression: P max = (Tjmax – Tamb) / θja The maximum output current (Imax) at a given value of Input voltage (VIN) and output voltage (V OUT) is then given by Imax =P max / (VIN -V OUT ) The value ofθja is strongly dependent upon the type of PC board used. Using the SC70 package it will range from approximately 280°C/W for a multi-layer board to around 450°C/W for a single sided board. It will range from 180°C/W to 300°C/W for the SOT23-5 package. To avoid entering the thermal shutdown state, Tj max should be assumed to be 125°C and Imax less than the over-current limit,(IOLIM). Power derating for the SC70 and SOT23-5 packages is shown in the following graph. Capacitor Selection and Regulator Stability The device is designed to operate with all types of output capacitor, including tantalum and low ESR ceramic. For stability over the full operating range from no load to maximum load, an output capacitor with a minimum value of 1/H9262F is recommended, although this can be increased without limit to improve load transient performance. Higher values of output capacitor will also reduce output noise. Capacitors with ESR less than 0.5/H9024are recommended for best results. The dielectric of the ceramic capacitance is an important consideration for the ZXCL Series operation over temperature. Zetex recommends minimum dielectric specification of X7R for the input and output capacitors. For example a ceramic capacitor with X7R dielectric will lose 20% of its capacitance over a -40/H11034Ct o 85/H11034C temperature range, whereas a capacitor with a Y5V dielectric loses 80% of its capacitance at -40/H11034C and 75% at 85/H11034C. An input capacitor of 1 /H9262F (ceramic or tantalum) is recommended to filter supply noise at the device input and will improve ripple rejection. The input and output capacitors should be positioned close to the device, and a ground plane board layout should be used to minimise the effects of parasitic track resistance. Dropout Voltage The output pass transistor is a large PMOS device, which acts like a resistor when the regulator enters the dropout region. The dropout voltage is therefore proportional to output current as shown in the typical characteristics. Ground Current The use of a PMOS device ensures a low value of ground current under all conditions including dropout, start-up and maximum load. Power Supply Rejection and Load Transient Response Line and Load transient response graphs are shown in the typical characteristics. These show both the DC and dynamic shift in the output voltage with step changes of input voltage and load current, and how this is affected by the output capacitor. If improved transient response is required, then an output capacitor with lower ESR value should be used. Larger capacitors will reduce over/undershoot, but will increase the settling time. Best results are obtained using a ground plane layout to minimise board parasitics.
