8 APPLIATION INFORMATION The NP565 low dropout linear regulator provides adjustable voltages at currents up to 1.5 A. It features ultra fast transient response and low dropout voltage. These devices contain output current limiting, short circuit protection and thermal shutdown protection. Input, Output apacitor and Stability An input bypass capacitor is recommended to improve transient response or if the regulator is located more than a few inches from the power source. This will reduce the circuit's sensitivity to the input line impedance at high frequencies and significantly enhance the output transient response. Different types and different sizes of input capacitors can be chosen dependent on the quality of power supply. A 15 F OSON 16SA15M type from Sanyo should be adequate for most applications. The bypass capacitor should be mounted with shortest possible lead or track length directly across the regulator's input terminals. The output capacitor is required for stability. The NP565 remains stable with ceramic, tantalum, and aluminumelectrolytic capacitors with a minimum value of 1. F with ESR between 5 m and 2.5. The NP565 is optimized for use with a 15 F OSON 16SA15M type in parallel with a 1 F OSON 1SL1M type from Sanyo. The 1 F capacitor is used for best A stability while 15 F capacitor is used for achieving excellent output transient response. The output capacitors should be placed as close as possible to the output pin of the device. If not, the excellent load transient response of NP565 will be degraded. GEN Adjustable Operation The typical application circuit for the adjustable output regulators is shown in Figure 2. The adjustable device develops and maintains the nominal.9 reference voltage between Adj and ground pins. A resistor divider network R1 and R2 causes a fixed current to flow to ground. This current creates a voltage across R1 that adds to the.9 across R2 and sets the overall output voltage. The output voltage is set according to the formula: out ref R1 R2 R2 IAdj R2 The adjust pin current, I Adj, is typically 3 na and normally much lower than the current flowing through R1 and R2, thus it generates a small output voltage error that can usually be ignored. Load Transient Measurement Large load current changes are always presented in microprocessor applications. Therefore good load transient performance is required for the power stage. NP565 has the feature of ultra fast transient response. Its load transient responses in Figures 13 through 16 are tested on evaluation board shown in Figure 19. On the evaluation board, it consists of NP565 regulator circuit with decoupling and filter capacitors and the pulse controlled current sink to obtain load current transitions. The load current transitions are measured by current probe. Because the signal from current probe has some time delay, it causes un-synchronization between the load current transition and output voltage response, which is shown in Figures 13 through 16. out Pulse + - in NP565 Evaluation Board RL + Scope oltage Probe Figure 19.

9 PB Layout onsiderations Good PB layout plays an important role in achieving good load transient performance. Because it is very sensitive to its PB layout, particular care has to be taken when tackling Printed ircuit Board (PB) layout. The figures below give an example of a layout where parasitic elements are minimized. For microprocessor applications it is customary to use an output capacitor network consisting of several capacitors in parallel. This reduces the overall ESR and reduces the instantaneous output voltage drop under transient load conditions. The output capacitor network should be as close as possible to the load for the best results. The schematic of NP565 typical application circuit, which this PB layout is base on, is shown in Figure 2. The output voltage is set to 3.3 for this demonstration board according to the feedback resistors in the Table 1. in 2 in out 4 out NP565 5 N Adj R k R k p Figure 2.

12 Protection Diodes When large external capacitors are used with a linear regulator it is sometimes necessary to add protection diodes. If the input voltage of the regulator gets shorted, the output capacitor will discharge into the output of the regulator. The discharge current depends on the value of the capacitor, the output voltage and the rate at which in drops. In the NP565 linear regulator, the discharge path is through a large junction and protection diodes are not usually needed. If the regulator is used with large values of output capacitance and the input voltage is instantaneously shorted to ground, damage can occur. In this case, a diode connected as shown in Figure 24 is recommended. in in 1N42 (Optional) out NP565 Adj 1 Adj R 1 R 2 out 2 Figure 24.
