These regulators feature extremely 400 TPS7225 TPS7230 low dropout voltages and quiescent currents compared to conventional LDO regulators. 300 TPS7233 Offered in small-outline integrated-circuit (SOIC) packages and 8-terminal thin shrink small-outline 200 TPS7248 (TSSOP), the TPS72xx series devices are ideal for cost-sensitive designs and for designs where board space is at a premium. 100 TPS7250 A combination of new circuit design and process innovation has enabled the usual pnp pass transistor to be replaced by a PMOS device.
- Typical Dropout Voltage Versus Output Current load current (see Figure 1). Since the PMOS pass element is a voltage-driven device, the quiescent current is very low (300 µA maximum
